The post has some Health, Safety, and environmental interview questions. if you are going through interview preparations, these questions will enhance your knowledge. For more health and safety-related free documents such as the method of statements, risk assessments, JSA’s. JHA’s, facility management, civil, electrical reports and forms, food safety documents, toolbox talks, HSE training, orientations in PowerPoint, and along with all these free downloads, you can also request any document you required for your project. When you request any health and safety and environmental document via our website at hsedocuments.com, we try to search for that document in our HSE Document library, if not found in the library, we request our professionals to prepare the requested document and upload it as soon as possible on our website.

7- What is a fire alarm system or fire control panel system how many types are there?
Answer: A fire alarm is an automatic electronic panel that will indicate when a fire occurs. The fire alarm is connected to the smoke detector and heat detector. When smoke comes down the detector will give the signal to the alarm panel and the alarm gives the indication water is 9.12 meters. Or a fire alarm control unit (FACU), is the controlling component of a fire alarm system. The panel receives information from environmental sensors (Heat detectors or smoke detectors) designed to detect changes associated with fire.
There are four primary kinds of panels: coded panels, conventional panels, Addressable Panels, and Multiples systems.
8- What is the difference between smoke and heat detector and how does it work?
Answer: Smoke Detectors: (SD) It detects the smoke if there is a fire on the worksite or building.
Heat Detector: (HD) It detects the temperature in case of fire.
9- What is Risk Assessment?
Answer: It is a systematic way to identify the hazards and to control those hazards for a specific task.
10- What is the work permit system and how many types are there?
Ans: PTW is a formed documented control procedure that takes account of all the expected interactions between the workers, the environment, and the associated hazards. There are seven types of PTW, they are: -
- Hot work permit
- Cold work permit
- Electrical work permit
- Working at the height of work permit
- Excavation work permit.
- Acid area work permit
- Vessel entry work permit.
- Definition of Hazard, Accident, and Near Miss?
Answer: Hazard: - Anything which has the potential to cause harm or damage to the property.
Accident: Unplanned unwanted events which result in harm or damage to property.
Near Miss: In an incident in which no injury or destruction.

- Preparing risk assignments.
- Monitoring.
- Regular audit.
17- What is a fire sprinkler system and how does it work?
Answer: A sprinkler system is installed inside the building. It is working under water pressure. On the end of pipelines, the sprinkler head is fitted the sprinkler head is rated to 68 degrees. In case of fire, the temperatures will increase and the sprinkler head will break and get sufficient water with pressure. The distance between the sprinkler head is 3 meters. The coverage area of the sprinkler water is 9.12 meters.
18- How many types of hazards are there and what are those?
Answer: There are five types of hazards.
- Physical Hazards: - PH-Caused by physical energy noise vibration.
- Chemical Hazards: - CH-Through chemical.
- Biological Hazards: - BH-Through microorganisms, bacteria, viruses fungi.
- Ergonomic Hazards: - EH-Caused by manual building.
- Cytological Hazards: - CH-Caused by work stress pressure.
19- How to inspect the fire extinguisher?
Answer:
- we need to check not obstructed.
- Check pressure.
- Check for the safety pin should be intact.
- No physical cracks.
20- What you will do if you find any unsafe conditions on the worksite?
