16. LOWER EXPLOSIVE LIMIT (LEL) :- The minimum concentration of particular combustible gas or vapour necessary to support its combustion in air is define as LEL.
# LEL senors measure explosivity, not toxicity.
2. UPPER EXPLOSIVE LIMIT (LEL) :- The maximum concentration of gas or vapour that will burn in air is define as the UEL.
# PART PER MILLION (PPM) :- Part's per million is commonly used unit of concentration for small value.
# PHOTO - IONIZATION DETECTOR (PID) :- Photo-ionization detector measure VOCs and other toxic gas in low concentrations from PPB ( parts per billion)

15. FLASH POINT:- The minimum temperature in liquid give enough vapour to ignite is called flash point.
OR
Flash point of a particular material is the lowest temperature at which vapour of the material under gose ignition in the presence of an ignition source.
# NOTE:- Flash point produce only flash in the presence of ignition source.
# Flash point of any liquid can change as the presence in the air around in change according to thermodonamic principle.
2. FIRE POINT:- Fire point of a particular material is lowest temperature at which the vapour of substance can keep burning when we remove the ignition source.
# NOTE:- Fire point continue to burn when we remove the ignition source.
# Flash point always less then the fire point.
3. AUTO IGNITION TEMPERATURE:- Auto ignition temperature of a substances is the lowest temperature at which it will spontaneously ignite in a normal atmospher without an external source of ignition.

14. LEADING AND LAGGING INDICATOR.
LEADING INDICATOR:- Leading indicators are process-oriented metrics, such as rate of implementation or conformance with policies and procedures that support the safety management system that is capable of predicting performance.
They often reflect proactive actions taken by the operator, such as proactive auditing or monitoring.
They usually relate to the controls on the below.
-Progress on annual OHS Improvement Plans
- Proactive
-Predictive
-Completed inspections and audits
-Training sessions conducted
-OHS meetings held
-Near misses reported
-Task observations completed
-LOTO/PTW audits conducted
-Risk assessment and hazard control activities
-Closed corrective actions
-Follow-up on recommendation tracking
LAGGING INDICATOR:- Lagging indicators are outcome-oriented metrics, such as incident rates or other measures of past performance.
A lagging indicator usually relates to outcomes (injuries or near-misses) or reactive actions (emergency response) and often involves incident notification to the regulator or
investigation by the operator.
They usually relate to the mitigating factors on the below.
-Fatality, injury, and incident frequency rates
-Reactive
-Outcome-based
-Vehicle accident frequency rate
-Employee compensation claims (GOSI)
-Equipment damage costs
-OHS non-compliance incidents
-Stakeholder complaints

13. Standards and Damage Acceptance for Webbing Slings:-
01. ISO 4878 (Industrial Lifting Slings):- Any damage affecting load-bearing capacity is unacceptable.Any visible damage, like cuts, tears, abrasions, or loose stitching, is considered a failure.
02. ΕΝ 1492-1 (European Standard for Lifting Slings):-
Reject slings with:-
Cuts or tears in the webbing.
Broken or worn stitching.
Heat damage or chemical exposure causing
discoloration or hardening.
Knots in the sling or damage to load-bearing labels.
03. OSHA 1910.184 (Slings):-
Slings must be inspected before each use.
Reject slings with:-
Cuts, frays, or broken fibers.
Damage due to heat, chemical exposure, or excessive wear.
Missing identification tags or markings.
04. ANSI/ASME B30.9 (Slings-Inspection and Use):-
States that any visible damage or evidence of degradation must result in immediate rejection.
Includes damage such as:-
Torn, frayed, or worn webbing.
Damaged stitching or repairs.
Burns, chemical stains, or stiffness from UV exposure.
05. Manufacturer Guidelines:-
Most equipment manufacturers specify zero tolerance for critical applications. Any amount of visible damage compromises safety, and continued use can result in liability or failure during operation.
Note:- Some people say 10% of damages to web slings are acceptable. Could you share your suggestions and standards?

12. "AUDIT :- Continuous Improvement Opportunity".
# Different types & Stages of Audits as Per ISO 45001-2018.
1.Joint Audit :- An Audit involves multiple organizations working together to conduct a single audit.
2. Combined Audit :- Conducting multiple types of audits within a single organization.
3. First Party Audit :- Audit in which an organization audits itself to check its conformance against particular process, system or standard being used.

9. Question :- what can be reason of insulation from safety point of view? What are health hazards ?
Answer :- From safety point of view industrial applications piping can be operating at extremely low or high temperatures.
There is potential danger in touching the piping if it is too hot or too cold. Insulation protects workers against burns from inadvertently coming in contact with the piping. Insulation brings a piping and valve system into a safe range for workers.
Second safety reasons are NOISE. Noise has a sneaky way of traveling through pipework. insulating the piping and valves is a valid method to reduce noise. It acts as an acoustic decoupler by preventing noise transfer when pipes pass through a fixed structure such as a floor or wall and lowers the noise of the materials moving through the systems.
HEALTH HAZARDS :-
1)Improperly Installed Attic Insulation Can Make You Sick
They have a sickening odor which can make people ill after long exposure.
2) insulation includes fiberglass, a common plastic that contains resins and fibers. As a result, people who handle or are exposed to this insulation can breathe in tiny bits of glass. After a while, those bits can get stuck in a person's lungs, leading to respiratory ailments.
