Precautionary Measures – H2S:
* a Sufficient number of escape masks shall be kept in areas where H2S is liable to
present.
* In case H2S presence is suspected in an area, the persons must put on an escape
mask immediately and the toxic gas test must be made immediately with an appropriate
detector to determined the concentration of H2S in air.
* Working person should be equipped with personal detectors and alarming devices
to alert in case of H2S presence.
Page: 10 of 35 HSE Questionnaire for Interview
* In case of H2S alarm, all personnel should vacate the area after donning the escape
set/breathing apparatus and report to the designated assembly point for
mustering.
* If working in H2S contaminated atmosphere must wear suitable BA set and work in
pairs to support and rescue each other in the event of difficulties.
* Know the wind direction and evacuate in the crosswind direction in case of H2S
leak.
* Never go to a low-lying area during H2S leak.

reported immediately to the supervisor and respective area fire station for arranging
rescue and support.
Q. How to treatment of persons affected by H2S?
Positive pressure breathing apparatus must be worn by any person attempting a
rescue.
* The victim must be immediately moved to fresh air, possibly in the upwind direction
of the gas leak. The rescuer must be outside the contaminated area before
removing his/her personal BA set.
* If the victim has stopped breathing, resuscitation must be started immediately,
using artificial respiration or a resuscitator if available. Resuscitation must be
continued until the victim starts breathing unaided or until qualified medical
assistance arrives. Medical help must be summoned as soon as possible.

work shift of 8 hours, to which workers can be exposed without respiratory protection
in a 40 hour workweek.
TLV-STEL:
Short Term Exposure Limit (STEL) when exposed only for a short period of 15
minutes. This maximum concentration can be allowed to breathe 4 times during 8
hours with a minimum 1-hour interval between exposures.
IDLH:
Minimum concentration of contaminant in the air which is Immediately Dangerous to Life
and Health (Note: Air supplied respirators are required in IDLH atmospheres.)

Q. What is Flash Point (FP)?
The minimum temperature at which a flammable mixture of gas or vapor in the air will
momentarily flash when a source of ignition (spark) is introduced.
Q. What is Auto-Ignition Temperature (AIT)?
The minimum temperature required to initiate self-sustained combustion of a solid, liquid or
gas in the absence of a source of ignition.
Q. What are LEL/LFL and UEL/UFL?
Lower Explosive Limit (LEL): or (Lower Flammable Limit)
Minimum concentration of vapor or gas in air which will burn when a source of ignition
(spark) is introduced.
Upper Explosive Limit (UEL): or (Upper Flammable Limit)
Maximum vapor/gas to air concentration above which flame propagation will not occur,
i.e. the mixture is “too rich” to burn.
Note-1: Flammable Gas Detectors (Meters) measure % LEL, hence actual LEL means
100% of full-scale reading of the meter. Below LEL (100% of meter reading), a
mixture is “too lean” to burn.
Note-2: LEL of airborne combustible dust: If the dust obscures vision at a distance of 5
feet (1.52 m) or less it is considered as at LEL (ex. Sulfur or coke).

CLICK HERE FOR 👉 FIRE TRIANGLE

Q. What is the different class of fire/types of fire?
Class of Fire: (As Per KOC)
Class A – Carbon-based combustible materials (wood, rubber, paper, fabric, etc.)
Class B – Liquid (petrol, oil, thinners etc.)
Class C – Gases (acetylene, propane, LPG, Butane etc.)
Class D – Metals (Sodium, potassium, magnesium) require a special extinguishing agents.
Class E – Fire involving energized electrical equipment as electrical cable, electrical
motor etc.

Q. What is the fire extinguishing principle?
Fire extinguisher principle involves eliminating one or more of the components forming a Fire Triangle.
Starving: The removal of fuel to the point so that nothing remains to burn.
Example: turn off valves.
Smothering: The removal of air or oxygen to point the so that combustion ceases.
Example: fire blanket, foam, and sand.
Cooling: Cooling of fuel to the point so that combustion vapors are no longer produced, and the temperature is dropped below the ignition point.
Example: water spray etc.
Inhibiting the Flame Chain Reaction:
It is represented by the fire tetrahedron shown below. In this method by arresting the chemical chain reaction in the flame zone, the combustion process is terminated, e.g. introduce a Dry Chemical Extinguisher, inert agent, etc.
Q. What is the transmission of heat?

Transfer of heat is responsible for initiation, continuation, and extinguishment of most fires.
Fire can spread by one or more of the following modes:-
Conduction: Heat from one body is transferred to another by direct contact.
Convection: Heat is transferred by a circulating medium either a gas or liquid.
Radiation: Heat is transferred from one body to another by heat rays a medium in between.
Q. Define Near Miss, Incident & accident? What is different between
Incident & Accident?
Near Miss: Near miss is an incident, which resulted in no injury or illness and/or damage
(loss) to people, assets, the environment, or Company reputation.
Example: A water tanker tilted.
Incident: Incident is any unwanted and unplanned occurrence/event which resulted or
could have resulted in physical injury or death to person or damage to property or environment.
Or
An undesired event that has caused or could have potentially caused personal injury, illness and/or damage (loss) to assets, production or harm to
environment or third party.
Example:
Accident: Accident is an undesired unplanned occurrence that resulted to an injury or death to a person or damage to property or environment.
It is occurring due to unsafe acts or unsafe conditions or a combination of both.
OR
The accident is an unexpected, unplanned and unwanted occurrence which is occurred by unsafe act and unsafe condition or combination of both, which can be resulted in injury to person and damage to property and environment.

Q. What is the different Hazardous Area Classification? (as per KOC)
What do you mean by Hazardous Area? What is Zone 0, 1 and 2.
Hazardous Area:
A hazardous area is a zone in which a flammable atmosphere may be present during normal operation or under abnormal conditions.
Classification of Hazardous Area:
Zone – 0: Zone in which a flammable atmosphere is continuously present or present for a
long period. (Typically more than 1000 hours/year.)
Zone – 1: Zone in which a flammable atmosphere is likely to occur in normal operations. (Typically 10 to 1000 hours/year)
