Q 4. Define Safety?
Freedom from risk or harm, loss or injury. Safety means protecting people, equipment, and the environment by following safety rules, managing risks early, and always aiming for zero harm.
Q 5. What is JSA?
JSA (Job Safety Analysis) is a document where we break a job into small steps, and for each step we write the hazards and the safety precautions. JSA helps us understand the safe way to do the job. It shows what dangers are involved and what we must do to avoid accidents.
Q 6. Who makes the JSA?
JSA is prepared by the Contractor’s Safety Department and approved by the Engineering Department and Saudi Aramco Project Management Team (PMT).

Examples of low risk activities:
- Minor sweeping
- Visual inspection
- Non-flash photography
- Taking a gas test
Q 16. What is LOTO?
LOTO (Lockout–Tagout) is a safety procedure used to stop a machine from starting accidentally. It protects workers from injury by locking and tagging the equipment before work starts.

- Slope Angle: 34°
- Most unstable soil, requires maximum sloping.
46. What is Excavation?
Excavation means digging or removing soil using hand tools or machines. It is the process of creating a hole, trench, or pit in the ground. Any excavation 1.2 meters or deeper is treated as a Confined Space (CS).

Q 70. What is the Difference Between Incident and Accident?
- Incident
An unwanted and unplanned event but it does not cause injury, damage, or loss. It is maybe a near miss or unsafe event without harm.
Example: A hammer falls from height but hits no one — this is an incident.
- Accident
An unwanted and unplanned event that results in injury, damage, or loss
Example: A hammer falls from height and injures a worker — this is an accident.
Q 71. Define Risk Assessment?
Risk Assessment is a process in which we:
- Identify hazards
- Find out who may be harmed and how
- Evaluate the level of risk
- Decide how to eliminate or control the risk
In simple words, It is a formal method to identify risks and then remove or reduce them to a safe level.
Examples of Risk Assessment:
- Before starting welding, checking fire hazards and deciding controls
- Inspecting an excavation for collapse hazards and planning shoring

- Sand has no flammability (cannot burn).
Q 74. Define Combustible?
A combustible material can burn, but it usually needs more heat compared to flammable materials.
Examples
- Wood – combustible
- Paper – combustible
- Diesel – combustible (needs higher temperature than petrol).
Q 75. Define Combustibility?
Combustibility is the measure of how easily a material can catch fire and burn.
Examples
- Paper has high combustibility (burns easily).
- Wood has moderate combustibility.
- Metal has low combustibility (very hard to burn).
Q 76. If work is low risk in a non-restricted area, which permit is needed?

Q 78. How do you treat a heat stroke victim?
Heat stroke happens when the body becomes too hot and cannot cool down. It is very dangerous and needs immediate first aid to prevent organ damage or death.
Steps to Treat a Heat Stroke Victim
- Move the person to a cool, shady place.
- Start cooling the body immediately:
- Remove extra clothing.
- Pour cool water on the skin or wet a cloth and place it on the body.
- Fan the person to help evaporation.
- Put ice packs under the armpits, neck, and groin.
- If the person is conscious, give cool water to drink.
- Monitor body temperature if possible. Try to lower it to around 38–39°C (101–102°F).
- Call emergency services (911 or 110) immediately. Follow their instructions until help arrives.
- Stay with the victim and keep cooling them continuously.
