2. Why is hazard reporting procedure important? Make a sample hazard report form.

Ans: Hazard reporting procedure: Hazards are common at the workplace. Some hazards may be communicated verbally to the supervisor, while some may require the Unarmed Security Guard to duly fill in a ‘hazard report form’ and submit it to the concerned authority. Acute hazards must always be reported to the supervisor or workplace health and safety officer immediately. An organisation for which security arrangements have been made will have specific procedures for tackling emergency situations, which are, usually, specified in the Emergency Procedures Manual.

Hazard report form: It is a common way of reporting hazards. This form helps maintain a record of a hazardous incident, and ensures that appropriate and timely action(s) is taken. It describes the nature and location of the hazard, who noticed it first, to whom it was reported and the action taken.

Subjective Questions:

1. Write a note on different kinds of fire extinguisher. 

Ans: Types of fire extinguisher:

(i) Water extinguisher: It works by eliminating the heat element. It is used only for Class A type fires as it may be hazardous in case of other fires. If water is used to douse Class B type fires, the flammable liquid may spread, whereas, in case of Class C fire, it may lead to an electric shock.

(ii) Foam extinguisher: It may be used to douse Class A and B type of fire but not Class C type fire.

(iii) Carbon dioxide extinguisher: It works by eliminating two components — oxygen supply and heat. It is used for dousing Class B and C type fires but is ineffective in case of Class A type fires.

(iv) Dry chemical extinguisher: It is effective in case of Class A, B and C type fires. Therefore, it is also called a ‘multipurpose dry chemical’ extinguisher. It creates a barrier between oxygen and fuel, and hence, douses the blaze.

(v) Wet chemical extinguisher: It works in case of Class K type fires (those caused by cooking oils, fats, etc.). It eliminates heat, and creates a barrier between oxygen and fuel.

(vi) Clean agent extinguisher: These use Halon and Halocarbon agents to interrupt the combustion process. They are commonly used for dousing Class B and C fires. They leave no residue when used, hence, the name ‘clean agent’. Larger clean agent extinguishers are used for dousing Class A type fires.

(vii) Specialist dry powder extinguisher: It creates a barrier between oxygen and fuel, thereby, dousing the fire. It is effective for Class D fire, involving combustible metals — lithium, magnesium or aluminium.

(viii) Water mist extinguisher: It cuts the heat element and may be used as an alternate to a clean agent extinguisher. It is mainly used for dousing Class A type fires. However, it may be used for dousing Class C type fires as well.

(ix) Cartridge operated dry chemical extinguisher: It is mainly used for dousing Class A type fires. It cuts oxygen supply to the fuel and extinguishes the blaze.

2. What is the importance of conducting a fire drill? 

Ans: Importance of Conducting a Fire Drill: 

(i) Familiarizes everyone with evacuation procedures: Fire drills teach people how to exit the building safely and quickly in case of a fire.

(ii) Reduces panic during emergencies: Regular practice helps people stay calm and avoid confusion during an actual fire.

(iii) Identifies weaknesses in the fire safety plan: Drills help spot problems in evacuation routes, alarms, or equipment that need fixing.

(iv) Training: Provides hands-on experience in responding to fire emergencies.

(v) Compliance: Meets regulatory requirements and standards.

3. What do you understand by electrocution? What would you do to rescue an electrocution victim?

Ans: When a person comes in direct contact with an electrical energy source, having a voltage high enough to cause current flow, one experiences an electric shock. Exposure to electrical energy may cause no harm at all, or severe damage and even death. Injury like burns, fibrillation, severe neurological damage, damage to the bones and respiratory system or death due to electric shock is called ‘electrocution’. Shocks caused by faulty electric appliances, equipment and cables may cause severe injuries and even lead to permanent disability. Therefore, one needs to observe utmost caution while working around machines or exposed electric cables. Safety depends on how one deals with a situation and one’s alertness.

If you come across an electrocution victim, here are the steps to safely rescue and help them:

(i) Do NOT touch the victim directly if they are still in contact with the electrical source. You could get shocked too.

(ii) Turn off the power supply immediately if possible. Switch off the main power or unplug the device causing the shock.

(iii) If you cannot turn off the power, use a non-conductive object (like a wooden stick, plastic rod, or dry cloth) to separate the victim from the electrical source.

(iv) Once the victim is free from the electrical source, check their responsiveness and breathing.

(v) If the victim is unconscious and not breathing, start CPR immediately.

(vi) Call emergency services immediately for professional medical help.

(vii) Keep the victim warm and monitor their condition until help arrives.

(viii) Do not move the victim unnecessarily unless there is an immediate danger.
