Hazard Communication & Chemical Safety

1
Hazard Communication Chemical Safety

• Based on OSHA Standard 1910.1200

2
We use many chemicals

• We want you to know how to use them safely
• You will learn about
• The Hazards of Chemicals
• Our Written Program
• How Chemicals are Labeled
• Safe Use of Chemicals
• Material Safety Data Sheets
• Basic Procedures for Spills
• Who you can ask for more information

3
Hazards of Chemicals

• There are 2 basic types of chemical hazards
• Physical Hazards
• Health Hazards
• The first rule of Chemical safety is "Know what
  you are working with and how to protect yourself
  and others

4
Physical Hazards

• Chemicals are classified as having Physical
  Hazards if they are
• Explosive
• Compressed Gas
• Combustible Liquids
• Flammable
• Unstable
• Water Reactive
• Oxidizers

5
Physical Hazards

• Some chemicals may be safe by themselves, but
  become dangerous when in contact with other
  substances.

6
Chemicals with Physical Hazards

• Used only by trained employees
• Stored in a safe manner
• Never mixed with other chemicals unless by an
  approved procedure

7
Health Hazards

• Chemicals are classified as being a health hazard
  if they
• Can cause cancer
• Are poisonous (toxic)
• Cause harm to your skin, internal organs, or
  nervous system
• Are corrosive - such as acids
• Cause allergic reactions after repeated exposure

8
Chemicals can enter the body through

• your lungs if you breath fumes, mists or dust
• your skin if liquid or dust touches or spills on
  you or splashes in your eyes
• your mouth if you eat after handling chemicals
• accidental swallowing of a chemical

9
Health Effects

• Some chemicals affect specific organs such as
  your kidneys, liver, reproductive or nervous
  system.

10
Our Written Hazard Communication Program provides

• Written information on hazards
• Lists Chemicals we use and their hazards
• System for ensuring chemicals are labeled
• Means to ensure we have an Material Safety Data
  Sheet (MSDS) for each chemical

11
Our Written Hazard Communication Program

• Lists who is responsible for the program
• Provides chemical specific safety training
  methods
• Tells you where to find chemical safety
  information
• You can see a copy of our written program by
  asking you supervisor

12
Labeling of Chemicals

• Chemical Labels provide information on Identity,
  Hazards and Safe Use
• All chemical containers are labeled by the
  manufacturer
• Our company may place additional labels on the
  containers

13
Labeling of Chemicals

• If chemicals are placed in another container,
  this new container must have a a label placed on
  it.
• All containers must be properly labeled

14
Uniform Labeling System

• Our Company Uniform Labels are used to ensure
  we have one labeling system.
• These may be placed on containers when chemicals
  are delivered to us or chemicals are transferred
  to other containers

15
2 Basic Uniform Labels

• HMIS - Hazardous Material Identification System
• NFPA - National Fire protection Association
• Both types must identify the
• chemical name and hazards

16
Uniform Labels

• Pictures may be used to identify hazards and
  required protection
• This Information may also be on the
  Manufacturers label

17
HMIS NFPA labels are very similar

• Both use colored boxes to identify specific
  hazards
• Numbers or codes in the boxes tell you the hazard
  value
• higher numbers higher hazard

18
NFPA HMIS Label Colors

• Red - Fire Hazard
• Blue - Health Hazard
• Yellow - Reactivity Hazard - explosive, unstable
• White - Special Hazards - corrosive, radioactive,
  water reactive, acid

19
NFPA Label..
The purpose of the NFPA 704 labeling system is to
provide a way of quickly identifying the various
fire related hazardous associated with a
particular material. The NFPA 704 "diamond" is
commonly found on bulk storage containers, but is
also widely used on chemical containers and MSDS
sheets.
20
NFPA Flammability Codes

• 4 Materials that will rapidly or completely
  vaporize at atmospheric pressure and normal
  ambient temperature, or that are readily
  dispersed in air and that will burn readily.

  boiling point below 100ºF.

21
NFPA Flammability Codes

  almost all ambient temperature conditions.
  Liquids with a flashpoint below 73ºF and a
  boiling point above 100ºF or liquids with a
  flashpoint above 73ºF but not exceeding 100ºF and
  a boiling point below 100ºF.

22
NFPA Flammability Codes

33
What do I do

• if there is no label or I cannot read the label?
• STOP - do not use the chemical
• TELL your supervisor
• READ the MSDS and have another label put on the
  container

34
Chemicals can be safely used if

• you know the hazards and how to protect yourself
• they are used only for approved purposes
• they are stored properlyyou use the correct
  personal protective equipment

35
Chemicals can be safely used if

• you do not eat in areas where chemicals are used
• you wash immediately if you come in contact with
  chemicals

36
Chemical Disposal

• Each chemical and container must be disposed of
  properly
• No container is truly "empty" unless properly
  cleaned
• Follow MSDS requirements for container disposal

37
Chemical Disposal

• Recycle unused chemicals
• Do not place hazardous chemicals in normal trash
  receptacles.
• Do not pour chemicals into sinks, onto the ground
  or in storm drains

38
Safe Storage

  storage lockers

39
Safe Storage

• Store acids in separate flammable storage lockers
• Do not store chemicals in a refrigerator used for
  food storage
• Do not store food in refrigerators used for
  chemical storage

40
In case of an emergency

• Implement the proper Emergency Action Plan
• Evacuate people from the area
• Isolate the area- keep other from entering
• Turn off ignition and heat sources
• Only trained employees are permitted to clean up
  spills

41
Material Safety Data Sheets (MSDS)

  chemical
• Check the PPE before use to make sure it is not
  damaged

52
Protecting Yourself

• Use face shield and Goggles if there is a splash
  hazard
• Use the proper respirator for dusts, mists and
  fumes

53
Protecting Yourself

• Use the right gloves when handling chemicals
• Properly clean and store your PPE after use
• Don't take PPE home - why risk exposing your
  family?

54
Stay safe when using chemicals

• Know what you are working with
• Know where MSDS are located and how to use them
• Ask your supervisor if you have questions
• Only trained employees may use chemicals

55
Stay Safe

• Make sure all containers are properly labeled
• Use the proper protective equipment
• Store chemicals only in approved areas
• Immediately report leaks and spills
• Dispose of used chemicals and containers properly
