Causes of fire

• Cryogenic Liquids
• Neither liquid nitrogen nor liquid air should be
  used to cool a flammable mixture in the presence
  of air because oxygen can condense from the air
  and lead to a potentially explosive condition.

Causes of fire

• ElectricalMulti-outlet plugs shall not be used
  unless they have a built-in circuit breaker. 
  This causes overloading on electrical wiring,
  which will cause damage and possible overheating.

Causes of fire

• Compressed Gas Compressed gases may be
  combustible, explosive, corrosive, poisonous,
  inert, or a combination of hazards.

5
Causes of fire

• Flammable-Liquid Storage Cabinets
• Cabinets designed for the storage of
  flammable liquids should be properly used and
  maintained.

If you discover a fire

• Operate the fire alarm.
• If you are carrying out an experiment, make sure
  your work area is safe by turning off all heat
  sources.
• Tell a member of staff.
• Leave the room as quickly as possible making sure
  all other people have left.
• Do not stop to collect personal belongings.

If you hear a fire alarm

• Respond immediately
• If your carrying out an experiment, make sure
  your work area is safe turning off all heat
  sources.
• Close all doors and windows.
• Quickly and quietly evacuate the building by the
  nearest exit.

Jim Streit

• According to Jim Streit, the Lab's fire marshal
  in Fire Protection (FWO-FIRE), these practices
  can include installing smoke detectors and
  changing batteries in them on a regular schedule
  creating muster areas outside the home and
  developing and practicing fire escape plans with
  all family members. "Families should develop and
  practice a fire escape plan, and everyone should
  know at least two ways out of each room of the
  house," said Streit. He added that smoke
  detectors should be present at all levels of the
  home and near all bedrooms.

Sprinklers

• Sprinklers has been proven in use for well over
  100 years and over 40 million are fitted
  worldwide each year.
• 99 of fires are controlled by sprinklers alone
  and
• 60 of fires were controlled by spray from no
  more than 4 sprinklers.
• Losses from fires in buildings protected with
  sprinklers are estimated to be 1/10 of those with
  unprotected buildings.

How sprinklers work

• Each sprinkler head will open when it reaches a
  specific temperature and spray the water on the
  fire. The hot gases from the fire are usually
  enough to make it operate. Only the sprinklers
  over the fire open. The others remain closed.
  This limits any damage to areas where there is no
  fire and reduces the amount of water needed.

11
Fire Doors

• Fire doors are typically made of steel or solid
  wood. They are provided with specially tested
  components including closers, latching hardware,
  and wired fire-rated glass windows. These doors
  create a fire wall. They can only perform
  properly when they are maintained well. Some fire
  doors are found in corridors and they close when
  they hear they fire alarm. They stop the fire
  from spreading.

Arrow rated fire doors

• Arrow rated Fire Doors provide a range of fire
  performances from 30 minutes up to 4 hours in
  accordance with BS476 Part 22.
• As well as offering reliable fire-resistance,
  Arrow rated Fire Doors are hygienically finished,
  easily cleaned, robust and suitable for all types
  of aperture. The range includes single and twin
  doors suitable for internal and external use.
• Arrow rated Fire Doors are constructed from a
  Zintec steel skin and cellular honeycomb core
  which are fully bonded and combined with locked
  seam joints to the vertical edges. This ensures a
  product of unequalled strength over all its
  competitors.
• Heavy-duty locks and handles can be provided
  where high security is a must
