FIRE SAFETY AND FIRE EXTINGUISHERS

Fire safety and fire extinguishers



Fire safety and fire extinguishers

Task 1:

Explosive Oxidizing

Extremely Flammable Toxic

Harmful/Irritant Corrosive

Radioactive

Task 3:

A:

Drilling aluminium

While drilling equilibrium, I took certain personal protective equipments (PPE) that included gloves, safety eyeglasses and hardhat

Acid etching a PCB:

Using a soldering iron:

I wore appropriate personal protective equipment when soldering, including eye

Protection, a long-sleeve shirt, long pants, heat resistant gloves and closed-toed shoes to protect the skin from hot solder spatters and drips (Todd 2009).

B:

Personal protective equipments while:

Using the gas and air torch

Personal Protective Equipment (PPE) such as eye protection, helmets, hand shields, and goggles are required to meet appropriate standards while using the gas and air torch.

Working with adhesives

I would wear personal protective equipment, including butyl rubber gloves. These gloves will protect my skin from irritation caused by the solvent. I would also wear safety goggles in case I might splash the solvent (Mousavi, Bagchi and Kodur 2008). Wearing an apron made from butyl rubber, would also be helpful for my protection.

Using aerosol paints

Moving heavy equipment

Task 4

There are six different types or classes of fire, each of which has extinguishers to tackle the specific types of fire. Newer fire extinguishers use a picture/labelling system to designate which types of fires they are to be used on.

Class A

Solid

 

Class B

Liquid

 

Class C

Gas

 

Class D

Metal

 

Class F

Cooking Oil

 

Electrical

Electrical

 

Additionally, the majority of fire extinguishers have a numerical rating which is based on tests conducted by professional fire-fighters that are designed to determine the extinguishing potential for each size and type of extinguisher (Griffith 2009).In the instance of class 'A' fires, the numerical value is the size of fire in cubic metres that the extinguisher can put out.

For class 'B' fires the numerical value represents the amount of litres of flammable liquid that can be extinguished.

Class 'C' fires have no numerical value as flammable gas is very difficult to measure in cubic metres - it depends on the ratio of gas to air there is in the local atmosphere.

Class 'D' fires have a numerical value, this represents size of fire in cubic metres that the extinguisher can put out.

'E' Class fires have no numerical value - please remember once the source of the electricity is shut down, the electrical fire will revert to a different class.

The numerical value in 'F' class fires is the same as in 'B' class fires - it represents the amount of litres of flammable liquid (cooking oils etc) that can be extinguished.

Fire ExtinguishersClass Of FireDescription

Water Fire Extinguisher WATER FIRE EXTINGUISHERS are especially designed for tackling Class A fires (wood, paper, straw, textiles, coal etc.).

Foam Fire Extinguisher FOAM FIRE EXTINGUISHERS are ideally suited where both class A & B fire risks exist. Aqueous Film Forming Foam or AFFF is particularly suited to fight liquid spill fires such as petrol, oil, fats, paints etc. and works by forming a film on the liquid to extinguish the fire. This extinguisher has also passed the electrical conductivity test at ...
