Basic Safety Questions
Q1.What is a hazard?
A: A hazard is anything with the potential to cause harm, injury, or damage. Hazards can be physical, chemical, biological, ergonomic, or psychosocial in nature.
Q2.What is risk?
A: Risk is the likelihood of a hazard causing harm combined with the severity of that harm. It is typically evaluated using a risk matrix.
Q3.What is an accident?
A: An accident is an unplanned, uncontrolled event that results in injury, damage to property, or loss. It is often the result of unsafe acts or conditions.
Q4.What is a near miss?
A: A near miss is an incident that could have caused harm but did not. Reporting near misses is critical to preventing future accidents.
Q5.What is safety?
A: Safety is the condition of being protected from hazards and risks that could cause harm. It involves implementing controls and systems to eliminate or reduce danger.
Workplace Safety
Q6.What is PPE?
A: PPE stands for Personal Protective Equipment — devices and garments worn to reduce exposure to workplace hazards. Examples include helmets, gloves, safety glasses, and high-visibility vests.
Q7.What is a toolbox talk?
A: A toolbox talk is a short, informal safety meeting conducted before starting work. It covers specific hazards, safe work procedures, and reminders relevant to the day's tasks.
Q8.What is a safety policy?
A: A safety policy is a formal document outlining a company's commitment to health and safety. It defines responsibilities, objectives, and the organisation's approach to managing workplace risks.
Q9.What is a safety audit?
A: A safety audit is a systematic inspection and evaluation of an organisation's safety management system. It assesses compliance, identifies gaps, and recommends improvements.
Q10.What is housekeeping in workplace safety?
A: Housekeeping refers to maintaining a clean, orderly, and organised workplace. Good housekeeping reduces slip, trip, and fall hazards and improves overall safety.

Q11.What is a permit to work system?
A: A permit to work (PTW) system is a formal written procedure used to control high-risk work activities. It ensures that all necessary safety precautions are in place before work begins.
Q12.What are the types of work permits?
A: Common types include hot work permits, cold work permits, confined space entry permits, electrical work permits, and work at height permits.
Q13.What is hot work?
A: Hot work is any work that involves open flames, sparks, or heat-producing operations such as welding, cutting, grinding, or brazing.
Q14.What is a confined space?
A: A confined space is an enclosed or partially enclosed area with limited entry and exit points, not designed for continuous occupancy, and which may have hazardous atmospheres or other dangers.
Q15.What is isolation in safety?
A: Isolation is the process of ensuring that equipment or energy sources are de-energised, locked out, and tagged before maintenance or repair work begins.
Fire Safety
Q16.What is fire?
A: Fire is a rapid chemical reaction (combustion) that requires three elements: heat, fuel, and oxygen — known as the fire triangle.
Q17.What are the classes of fire?
A: Fires are classified as: Class A (solids like wood and paper), Class B (flammable liquids), Class C (flammable gases), Class D (combustible metals), and electrical fires.
Q18.What is a fire extinguisher?
A: A fire extinguisher is a portable device used to control or extinguish small fires. Different types (water, foam, CO₂, dry powder) are suited for different fire classes.
Q19.What is the PASS method?
A: PASS is the technique for using a fire extinguisher: Pull the pin, Aim at the base of the fire, Squeeze the handle, and Sweep from side to side.
Q20.What is the fire triangle?
A: The fire triangle represents the three elements needed for combustion: heat, fuel, and oxygen. Removing any one element extinguishes the fire.
Construction Safety
Q21.What is work at height?
A: Work at height is any work performed above ground level where a person could fall and sustain injury. It requires risk assessments, guardrails, harnesses, or other fall protection.
Q22.What is scaffolding?
A: Scaffolding is a temporary elevated structure used to support workers, tools, and materials during construction, maintenance, or repair at height.
Q23.What is excavation?
A: Excavation is the process of removing earth to create a trench, pit, or foundation. It requires planning for cave-ins, utilities, and water ingress.
Q24.What is shoring?
A: Shoring is the process of temporarily supporting trench walls, building walls, or structures to prevent collapse during construction or excavation.
Q25.What is barricading?
A: Barricading involves using barriers, tapes, or signage to restrict access to hazardous areas on a worksite, protecting workers and the public.

Q26.What is earthing (grounding)?
A: Earthing is the process of connecting electrical equipment to the ground to prevent electric shocks. It provides a safe path for fault current to flow to earth.
Q27.What is an electrical hazard?
A: An electrical hazard is any dangerous condition where contact with energised equipment or conductors could result in electric shock, burns, or fire.
Q28.What is lockout/tagout (LOTO)?
A: LOTO is a safety procedure used to ensure that equipment is properly shut off, isolated from energy sources, and tagged before maintenance to prevent accidental start-up.
Q29.What is a short circuit?
A: A short circuit occurs when an abnormal, low-resistance connection forms between two points in an electrical circuit, causing excessive current flow and potential fire or equipment damage.
Q30.What is insulation?
A: Insulation is a non-conductive material that covers wires and electrical components to prevent current leakage, electric shock, and short circuits.
Oil & Gas Safety
Q31.What is H₂S gas?
A: Hydrogen sulphide (H₂S) is a highly toxic, flammable, colourless gas with a characteristic rotten-egg smell, commonly found in oil & gas operations.
Q32.What is gas testing?
A: Gas testing involves measuring atmospheric gas levels (oxygen, flammable gases, toxic gases) before entering a confined space or hazardous area to ensure it is safe.
Q33.What is a flare system?
A: A flare system is a safety device used in oil & gas facilities to safely burn off (combust) excess or waste gases that cannot be recovered or recycled.
Q34.What is SIMOPS?
A: SIMOPS (Simultaneous Operations) refers to multiple work activities happening at the same time and location, requiring careful coordination to prevent incidents.
Q35.Why is PTW important in oil & gas?
A: The Permit to Work system is critical in oil & gas because of the high-risk nature of operations. It ensures all hazards are identified and controlled before work begins.
General Safety
Q36.What is incident reporting?
A: Incident reporting is the process of formally documenting accidents, near misses, and unsafe conditions so they can be investigated and preventive measures implemented.
Q37.What is first aid?
A: First aid is the immediate, temporary care given to an injured or ill person before professional medical help arrives. It can be life-saving in emergencies.
Q38.What is ergonomics?
A: Ergonomics is the science of designing workstations, tools, and tasks to fit the physical capabilities of workers, reducing strain and musculoskeletal injuries.
Q39.What is safety training?
A: Safety training is the process of educating workers about workplace hazards, safe work practices, emergency procedures, and the use of protective equipment.
Q40.What is an emergency response plan?
A: An emergency response plan is a documented procedure outlining the actions to take during emergencies such as fires, chemical spills, natural disasters, or medical emergencies.
