3Introduction
- It is not one of the mandates of the Canadian
Coast Guard Auxiliary to assist with oil spills. - In addition most vessels are RHIBs, and the tube
materials do not react well with oil . - This presentation is primarily for information
only.
4Safety Overview
5Safety Overview
- There are numerous kinds of shoreline cleanup
methods, each involving a variety of worker
skills and work site hazards. - It is important that the response organisation is
aware of their personnels skills, health, and
accident notification information.
6Safety Overview
- It is the employers responsibility to ensure that
their workers - have safe working conditions
- know and practice safe operating procedures
- are supplied with appropriate personal protective
equipment and clothing, and are trained in its
use
7Safety Overview
- Are aware of emergency communications,
transportation, facilities and supplies
8Safety Overview
- Safety is the result of cooperation, everyone
working a safe manner and watching out for each
other. - The Supervisor will ensure that site specific
hazards are identified and that employees are
instrcuted in the safe use of any additional
equipment they may reqiuire, such as respirators,
radios, fire extinguishers, etc.
9Safety Overview
- The employee is responsible for
- Know their job
- Know who to report to
- Work safely
10Safety Overview - Site Orientation
- Supervisors will conduct site specific hazard
assessments, so that can orient the employee to - Work location
- Specific Hazards
- Safety Procedures
- Emergency Communications
11Safety Overview - Site Orientation
- The supervisor should spend a few minutes with
each cleanup crew each morning reviewing safety
issues. - These daily pre-job meetings are a good
opportunity for employees to ask questions and
raise concerns with their supervisor.
12Safety Overview - General Safety Guidelines
- Before the employee begins work
- Report to their supervisor
- Be aware of their work location
- Clearly understand assigned activities
- Ensure they are trained and fit
- Be sure their buddy is available to provide
assistance - do not work alone
13Safety Overview - General Safety Guidelines
- Know location of First Aid supplies and qualified
medical attendants - Know location of radio/ line communication
systems - Know emergency transportation procedures
- Be aware of any hazards related to the working
environment
14Safety Overview - General Safety Guidelines

- Use the safety materials, equipment, devices and
clothing intended for employee protection - Follow safe job procedures
- Report anything that is felt to be hazardous or
potentially hazardous
15Safety Overview - General Safety Guidelines
- Report accidents immediately to their supervisor
- Do not wander off the work site, in remote areas
where one might get lost, or in populated areas
as it may be considered trespassing
16Safety Overview - Buddy System
- The Buddy system involves a minimum of two people
working as a team within the team. - Three Simple Rules
- Keep ones buddy insight at all times
- Always be able to communicate with their buddy
verbally or with universal hand signals
17Safety Overview - Buddy System
- Watch their buddy for signs of fatigue or
exposure to cold or heat - Alert the buddy to these and other work related
hazards
18Safety Overview - Universal Hand Signals
- Signal Meaning
- Hand clutching throat Out of air
- Cant breath
- Hands on top of head Need assistance
- Thumbs up Okay
- I understand
- Im alright
- Thumbs Down No
- Negative
- Grip partners wrist or place both Leave area
immediately - hands around partners wrist
19Safety Overview
- Remember work as a team and work safely
20Characteristics of Petroleum Products
21(No Transcript)
22General Hazards of Petroleum Products
- Petroleum products that could reach our
shorelines as a result of a marine oil spill
include - Light to volatile oils, such as gasoline
- Moderate to heavy oils, like diesel, lubricating
oils and Bunker C.
23General Hazards of Petroleum Products
- During the site orientation, it is the
responsibility of the supervisor to inform you of
the type and nature of the oil being handled, and
the clean up chemicals you might be exposed to.
24(No Transcript)
25Material Safety Data Sheet
- The supervisor is responsible for providing
information on the dangers associated with the
various petroleum products or clean up chemicals
and solvents that may be come in contact with.
All instructions for self protection against
exposure to these substances can be found on a
Material Safety Data Sheet.
26Material Safety Data Sheet
- There is a right to know about all dangers
related to any hazardous materials present at a
clean up site. The supervisor has access to
copies of Material Safety Data Sheets which will
be made available on request.

33Properties of Petroleum
- Petroleum is an organic liquid primarily
containing hydrocarbons with smaller percentages
of sulphur, nitrogen and oxygen. Trace metals can
also be found. The constituents can be vapour,
liquid or solid.
34Properties of Petroleum
- Gaseous and volatile liquid elements are highly
flammable and toxic - Crude petroleum which is weathered is not
flammable
35Properties of Petroleum
- As the spilled petroleum becomes weathered, it
become emulsified and forms a mousse like
consistency. - This material adheres to rocks, logs, wharves and
other objects, creating a slippery hazard for
shoreline workers.
36Properties of Petroleum
- During some of oil spill clean up operations, one
may be exposed to some petroleum products such as
solvents or harsh detergents that may be used.
The application of these substances will only be
done by trained specialists.
37Petroleum Vapours
- The most basic safety consideration related to
petroleum products is how recent the spill is .
If it is fresh, there may be a lot of explosive
vapours, or vapours that are very unhealthy to
breathe.
38Petroleum Vapours
- It is important to be aware of the hazards
associated with vapours and obtain approval from
the supervisor before going into a work site. - Petroleum vapours are generally heavier than air.
Even light gases may, when cold, be initially
heavier than air.
39Petroleum Vapours
- Vapours tend to flow to and accumulate in low
places such as - Caves Holes Pits
- Trenches Sewers Drains
- Inside dykes Under docks
- In the bottom of vessels
- Under piled logs
40Petroleum Vapours
- Be aware.
- Vapours can travel great distances. The dangers
are not always apparent for example, vapours can
be trapped beneath a hard crust and released
during shoreline cleaning. - Therefore it is important that one works only in
the areas posted safe for entry.
41Controlled Sites
- Certain areas of a shoreline clean up operation
are controlled sites. Only authorized and
trained personnel may enter these areas. They are
generally marked by yellow tape or signage. - Do not cross any barrier unless authorized
42Controlled Sites
- Encourage spectators to keep clear of the
operation and hazards involved - Inform your supervisor if you suspect
unauthorized people on the work site
43Confined Spaces
- Confined spaces such as caves and under piles of
logs pose a particularly serious vapour exposure
concern for shoreline workers.
44Confined Spaces
- Confined spaces may accumulate harmful vapour
concentrations from decomposing organic matter,
equipment exhaust fumes and spilled oil, thereby
reducing the amount of oxygen in the air
45Symptoms of Exposure
- The following list outlines some general signs
and symptoms that indicate vapour exposure - Dulled sense of smell Nausea
- Mental confusion Dizziness
- Shortness of breath Headaches
- Loss of consciousness Eye irritation
- Diminished sense of responsibility
46Symptoms of Exposure
- Everyone has different tolerance levels to
vapours. - If you are at all bothered by petroleum vapours
report immediately to the supervisor. Medical
attention may be required.
47Hydrogen Sulphide
- Hydrogen Sulphide is a toxic vapour associated
with some petroleum products. It can be lethal. - At lower concentrations, the vapour smells like
rotten eggs. First you smell it, then you dont,
but it could still be there. Hydrogen Sulphide
dimishes the sense of smell by attacking the
nervous system.
48Hydrogen Sulphide
- Remember, the absence of smell does NOT mean the
absence of petroleum vapour. If there is a danger
of hyydrogen sulphide vapours being present,
frequent testing of the clean up site will be
done.
49Hydrogen Sulphide
- Safety Precautions
- Work upwind from oiled areas
- Do not assume that gases and vapours are harmless
because they lack odour - Do not enter confined spaces until tested and
posted safe for entry - If instructed, use approved respirators according
to directions provided
50Hydrogen Sulphide
- While it is important for ones safety to be
aware of the dangers associated with petroleum
vapours, rest assured the dangers of working
with these products diminishes from the time the
spill occurs. - Workers are not permitted onto the work site
until the area has been thoroughly tested and
posted safe for entry.
51Exposure to Petroleum Products
- Common routes of exposure
- Inhalation
- Aspiration
- Ingestion
- Skin contact
52Inhalation
- Inhalation of petroleum products is the act of
drawing fumes or vapours into the lungs
53Aspiration
- Aspiration is the act of breathing petroleum
products, in liquid form, into the lungs. - Aspiration of petroleum products may cause
serious lung problems such as pneumonia or
pneumonia edema, and can be fatal.
54Aspiration
- Pneumonia edema is the build up of fluid in the
lungs, which can actually drown the respiratory
system. - Petroleum may be aspired by
- Falling into petroleum laden waters
- Breathing petroleum mist or spray
55Ingestion
- Inadvertent ingesting of oil can occur when food
or cigarettes are handled with contaminated.
Always wash with soap and water before eating or
smoking. - If a considerable of petroleum is ingested, do
not induce vomiting. Report to the supervisor.
Medical attention may be required.
56Skin Contact
- Skin contact is usually the main exposure to oil
during shoreline clean up operations - Any petroleum product can cause skin cause skin
problems when absorbed directly through the skin
layers, hair follicles and glands.
57Skin Contact
- Contact with the natural degreasing agents in
most petroleum products can cause - Dermatitis
- Oil Acne
- Prolonged exposure to petroleum products can lead
to harmful short and long term health effects
58Skin Contact
- Measures to prevent exposure
- Wear oil resistant gloves with cotton inner
gloves - Apply protective gels and creams that reduce skin
penetration and improve skin cleaning - Wear oil resistant coveralls or rain gear
- Wear approved footwear
59Skin Contact
- Wear approved eye or face protection
- When using rags or sorbent pads to remove
splashes, change them frequently - Do not keep oily rags or sorbent pads in your
pockets
60Skin Contact
- Response to skin contact with petroleum products
- Remove it as quickly as practical
- Use soap and water, or specially prepared cleaner
- Do not use harsh soaps. They cause skin
irritation
61Other Precautions
- Warming Fires
- Warming fires can only be lit if you have
approval from the supervisor. While comforting,
these fires can be a source of ignition for oily
clothing, wastes and other debris. - Due to the potential of inhaling emissions, do
not burn any oily wood or debris in a warming
fire.
62Other Precautions
- Smoking
- Smoking is not permitted on the work site, due to
the potential of explosion. Smoking is only
permitted in designated areas. - Lighters and Matches
- Do not carry lighters or matches onto the work
site.
63Other Precautions
- Electronic Equipment
- Where designated by the site safety supervisor,
intrinsically safe equipment, hand held radios
and flashlights will be utilized at a work site. - Do not bring electronic equipment or flashlights
onto the work site unless approved by the
supervisor

65Personal Protective Equipment
66(No Transcript)
67Personal Protective Equipment
- The petroleum products and crude oils that you
may encounter on a shoreline cleanup operation
may contain substances that can cause harmful
short and long term health effects. - The personal protective equipment and clothing
assigned is designed to help reduce the chances
of exposure to these substances .
68Types of Personal Protective Equipment
- Approved face mask and eye protection must be
worn when there is any risk of face or eye injury - During sunny periods tinted safety glasses and
sunscreen that provide high UV protection are
recommended.
69Types of Personal Protective Equipment
- Approved protective footwear must be worn by all
response personnel while on the work site. - Check that footwear is approved with the
supervisor.
70Types of Personal Protective Equipment
- Respiratory protection is generally not required
for a shoreline cleanup operation - In any instance where protection from vapours is
required, the employee will be provided with
respiratory protection and instructed in its use.
71Types of Personal Protective Equipment
- Approved hearing protection should be used in
high noise level areas such as around heavy
equipment, aircraft, operating vac-trucks,
generators, engines and powerpacks - Properly worn hearing protectors reduce noise
exposure without affecting voice communications.
72Types of Personal Protective Equipment
- Approved head protection is required where there
is potential of being struck from above or
striking something overhead.
73Types of Personal Protective Equipment
- Oil resistant gloves will be worn by all response
personnel to prevent oil contamination and reduce
skin exposure and abrasions.
74Types of Personal Protective Equipment
- Gloves may need to be taped to sleeves to prevent
seepage. Cotton gloves are generally worn inside
the outer gloves. For those with particularly
sensitive skin, a protective gel or cream can be
applied to the hands.
75Types of Personal Protective Equipment
- Approved lifejackets or Personal Flotation
Devices - These include
- Floater coats
- Floater vests
- Floater suits
76Types of Personal Protective Equipment
- Approved lifejackets or Personal Flotation
Devices must be worn at all times when there is a
risk of falling in the water.
77Types of Personal Protective Equipment
- Protective outerwear such as oil resistant
coveralls or rain gear should be worn by all
response personnel to prevent oil contacting the
skin. - Insulated inner clothing is the employees
responsibility. Wear well insulated inner
clothing such as woolen socks and sweaters as
required.
78Decontamination and Inspection
- During work it is very likely that petroleum
products will get onto the personal protective
equipment and clothing. - These contaminants should be removed after every
shift.
79Decontamination
- Wipe off any oil with a sorbant pad or clean rag
- Inspect the personal protective equipment and
clothing for rips, tears or other damage - Do not dispose of or take away worn personal
protective equipment or clothing
80Decontamination
- Let the supervisor know of ripped or worn
personal protective clothing so that accurate
inventory of materials and clothing can be
maintained. The employee will be resupplied as
needed.
81Decontamination
- Do not take personal protective equipment or
clothing home. Personal protective equipment and
clothing will be maintained and laundered by
designated personnel.
82Decontamination
- Wear the personal protective equipment and
clothing properly as it is for the employees
protection and safety. Take good care of it, and
it will take good care of you.

86Working Environment
- To be able to work safely and to be safe at a
shoreline clean up operation, it is important
that the employee knows and understands the
environmental and work site hazards you may be
exposed to.
87Working Environment
- Some of the hazards that may be encountered
include - Slippery surfaces
- Poor weather conditions
- Noise exposure
- Wildlife
- Drugs, alcohol and unauthorized firearms
88Common Injury Causes
- Slips, trips, falls and strains are the most
common cause of worker injury during a shoreline
clean up operation
89Common Injury Causes
- Hazards
- Getting on and off boats (on the shore or at the
dock - Walking on rough terrain
- Walking on beaches slippery with oil, seaweed or
ice - Handling oily wastes and hand tools
90Common Injury Causes
- Preventative measures
- Wear approved footwear
- Do not climb rocks
- Warn co-workers of potential dangers or hazards
- Avoid stepping on hoses, wires and ropes -
theymay be under tension and can move or tangle
unexpectectly
91Common Injury Causes
- Handle equipment properly
- Do not overlaod the bags with watse material
- Lift with your legs, not you back
- Ask buddies for help if it is needed
- Rest when necessary
92Shoreline Terrain
- Rock slides occur around vertical, sleeply sloped
shoreline and undercut banks. Warm temperatures
can loosen rock from underlying snow or thawing
ground. Debris from previous slides is a good
indication of danger. - Unstable logs can roll unexpectently when walked
on, crushing or pinning one or those in the
vicinity.
93Shoreline Terrain
- Wet or oiled logs can extremely slippery.
- Rising tides can trap you on the beach, blocking
off escape route at high water. - Ocean swells may create the danger of workers
being washed off the shoreline.
94Shoreline Terrain
- Safety
- Wear approved footwear
- Wear approved lifejackets of personal flotation
devices where there is any risk of falling into
the water - Avoid steeply banked shores and beach heads
95Shoreline Terrain
- Avoid areas where there is debris from previous
slides - Be sure logs are stable before walking on or near
them - Be cautious around exposed shoreline areas to
prevent being swamped by high waves or ocean
swells
96Shoreline Terrain
- Know the tidal information for the area you are
in and always be aware of possible escape routes - Check the natural shoreline high tide markers,
such as washed up debris, loose sea matter, and
tide lines on rock walls
97Poor Weather Conditions
- Weather and sea state vary throughout the country
because of the influence of large bodies of water
and geographical land forms. Be prepared for the
unexpected a well as the forecast weather
conditions
98Poor Weather Conditions
- Poor weather indications include
- High winds
- Fog
- Snow
- Rain
- Hot and cold temperatures
99Hypothermia
- Hypothermia is
- The lowering of the bodys core temperature below
the normal level. This can lead to
unconciousness, internal injuries or death if not
properly treated. - Cold, wet, windy weather increases the threat of
hypothermia, if one is not properly dressed
100Hypothermia
- The following factors can increase the threat of
hypothermia if one is not properly dressed - Wet clothing
- Immersion in cold water
- Exposure to wind chill factors
- Low temperatures
101Hypothermia
- Typical signs of hypothermia are
- Excessive shivering
- Slurred speech
- Mental confusion
- Pulse and respiration decrease as severity
increases
102Hypothermia
- Preventative measures
- Monitor oneself and ones buddy for signs of
fatigue and other signs ov overexposure - Dress properly. The supervisor will inform the
crew of the appropriate personal protective
equiopment and clothing to wear when exposed to
the cold
103Hypothermia
- It is the workers responsibility to wear well
insulated inner clothing, such as wool socks and
sweaters as required - If necessary, stop work and take time to recover
- Report any of these symptoms immediately to the
supervisor. Medical attention may be required
104Heat Exhaustion
- Heat exhaustion occurs when
- Excessive sweating causes a depletion of body
fluids - Conditions prevent the evaporation of sweat to
cool the body (high humidity)
105Heat Exhaustion
- Hazards
- Personal protective equipment or clothing
reducing ventilation and may lead to heat
exhaustion or heat stroke - Strenuous work in an area of high humidity
106Heat Exhaustion
- Typical signs of heat exhaustion are
- Pulse, weak and rapid
- Respiration, rapid and shallow
- Sweating
- Nausea
- Skin, cold and clammy
- Headaches
- Dizziness
107Heat Exhaustion
- Loss of consciousness
- Preventative measures
- Watch oneself and ones buddy for signs and
symptoms of overexposure - If necessary, stop work and take time to recover
108Heatstroke
- Prolonged exposure in a hot, humid, poorly
ventilated environment puts stress on the body as
it attempts to cool itself - Heatstroke occurs when the bodys temperature
regulatory system fails, sweating ceases and the
body temperature rises rapidly
109Heatstroke
- Symptoms of heatstroke include
- Rapid pulse
- Breathing - deep, noisy
- Dry, hot flushed skin
- Headaches, dizziness
- Mental confusion
- Nausea and vomiting
- Convulsions
110Heatstroke
- Preventative measures
- Watch oneself and ones buddy for sign and
symptoms of fatigue and overexposure - If necessary stop work and take time to recover
111Heatstroke
- Report any of these symptoms immediately to the
supervisor. Medical attention may be required
112Noise Exposure
- Noise exposure from boats, generators, pumps,
aircraft, winches and other commonly used
equipment can be reduced with proper hearing
protection. - Work extra carefully around noise. Be aware of
and be prepared to use universal hand signals to
communicate.
113Wildlife
- Wildlifes strong survival instinct can lead to
serious physical injury to their captors. - Distressed birds
- React to handling by striking out and pecking at
any area within reach, such as the hands or eyes.
114Wildlife
- Otters
- Can also react in a dangerous fashion, but with
more ferocity and extremely painful results.
115Wildlife
- All wildlife capture and treatment must be left
to personnel trained and equipped in wildlife
rescue, such as members of the Canadian Wildlife
Service
116Wildlife
- Bears, cougars and wolves
- They are common to remote shoreline areas.
Generally the reason they are on the beach is to
forage for food. - Being disturbed may cause them to react
aggressively. Be aware that all wild animals are
a danger.
117Wildlife
- Safety Precautions
- Do not attract the animals by feeding them or
leaving open food or garbage at the work site - If a large wild animal is seen in the area, l
eave and report to the supervisor
118Wildlife
- Domestic Animals
- Dogs have been kn own to react violently with
people trespassing on their territory
119Wildlife
- Vermin
- Be aware of any vermin such as rats, mice or
snakes that may be present on the work site. Be
especially cautious when working around docks and
wharves. Although small, these creatures can
inflict painful bites.
120Drugs, Alcohol and Unauthorized Firearms
- These man-made potential hazards are not
conducive to a safe safe shoreline clean up
oeration, and are therefore NOT PERMITTED on the
work site.
121Drugs, Alcohol and Unauthorized Firearms
- Drugs (Substance Abuse)
- Only over the counter and prescription medication
that will not cause drowsiness and impair your
ability to work, are permitted on the work site. - Workers must advise their supervisor of any
medical conditions or medications they may be
taking.
122Drugs, Alcohol and Unauthorized Firearms
- Alcohol
- Alcohol is not permitted on the work site
- Drunkenness will not tolerated
123Drugs, Alcohol and Unauthorized Firearms
- Unauthorized Firearms
- Only authorized personnel, such as enforcement
oficers, or those assigned the task of providing
protection from dangerous wildlife, are permitted
to carry firearms.
124Drugs, Alcohol and Unauthorized Firearms
- Report the use of illegal drugs, alcohol or the
presence of unauthorized firearms to the
supervisor.
125Equipment and Transportation
126Equipment and Transportation
- Shoreline clean up operations often involve the
use of a large variety of eequipment and types of
transportation. This type of equipment should
only be handled by experienced, trained personnel.
127Helicopters and Fixed Wing Aircraft
- When approaching or departing a helicopter or
fixed wing aircraft - Do not approach, leave or board until signalled
to do so by the pilot - Approach and leave the helicopter from the front,
always within view of the pilot

required to be worn in fixed wing aircraft, but
sufficient suits must be provided for all on
board.
133Boat and Water Operations
- Safety precautions
- Wear an approved floatation device or life jacket
- Always follow instructions given by the boat
operator - Handle ropes carefully
- Get on and off boats safely and carefully
134Boat and Water Operations
- While all water operations and related safety
gear are governed by applicable government
regulations, its still your responsibility to
access boats in a safe manner and abide by the
operators instructions. - Check with the supervisor if there is any
uncertainty about the life jacket or personal
floatation device is approved.
135Land Transportation
- Bulldozers, trucks and other machinery used on
the work site can be hazardous. - Three basic rules to follow when working around
heavy machinery are - Never walk behind the equipment while it is being
operated
136Land Transportation
- Never walk where the operator cannot see
- Keep an eye on the machinery at all times
137Hand Tools
