LS : What are the some important safety terminologies ?

IMPORTANT  SAFETY TERMINOLOGIES

Here are some important terminologies to remember which we come across in industrial safety.

1. ASPHYXIATION: - Asphyxiation occurs when body tissues do not receive enough oxygen. The blood oxygen level should be sufficient for normal tissue respiration.
2. ASPHYXIA: - Suffocation from lack of Oxygen.
3. AUTO — IGNITION TEMPERATURE: - The lowest temperature at a flammable gas, liquid or vapor — air mixture will ignite on it’s own or contact with hot surface without spark or flame.
4. CHEMICAL BURNS :- Burns caused by chemicals.
5. COLD BURNS:- Burns caused by liquified gases which are below zero degree C. 
6. COMBUSTIBLE:- Able to catch fire and burn.
7. COMBUSTIBLE LIQUIDS:- Liquids with a flash point above 37.8 C and below 93.3C
8. FLAMMABLE: - Any substance that is easily ignited, burns intensely or has a rapid rate of flame spread.
9. FLAMMABLE LIQUID:- Liquid having flash point below 37.8 C
10. FLASH POINT:- The lowest temperature at which a fluid gives off enough vapor to form a mixture with air and produce flame when a source of ignition is present.
11. EXPLOSIVE LIMIT:- The lower and upper limit of flammability of a gas or vapor at ambient temperatures in percentof the gas or vapor in air by volume.
12. FLASH BLINDNESS:- Temporary visual disturbance resulting from viewing an intense light source.
13. SPONTANIOUSELY COMBUSTIBLE:- A material that ignites as a result of retained heat from processing, or which will oxidize to generate heat and ignite, or which absorbs moisture to generate heat and ignite.
14. OXYGEN DEFFICIENCY:- An atmosphere having less than the percentage of oxygen found in normal air.
15. PERMISSIBLE EXPOSURE LIMIT(PEL):- The permissible concentration of air contaminants to which a worker can be exposed eight hours a day, forty hours a week , over a working life time (30 yrs.) without adverse health effects.
16. SHORT TERM EXPOSURE LIMIT(STEL):- The airborne concentration of a material to which any one can be exposed for a continuous 15 minute exposure period without adverse effects.(maximum four such exposures with at least 60 minutes between exposure periods are safe). Eg. Alarm set points of Chlorine and Ammonia.
17. PPM:- Parts per million by volume of vapor or gas or other contaminants.
18. RESPIRATOR:- A device to protect the wearer from inhalation of harmful contaminants.
19. PINCH POINT:- Any point at which it is possible to be caught between the moving parts, stationary parts or material being processed.
20. SCBA:- Self Contained Breathing Apparatus ( Supply or means of respirable air, oxygen or oxygen generating equipment.)
21. SPONTANEOUSELY COMBUSTIBLE:- A material that ignites as a result of retained heat from processing, or which will oxidize to generate heat and ignite, or which absorbs moisture to generate heat and ignite.
22. Threshold Limit Value (TLV)
23. LEL/ HEL Lower Explosive limit/ higher explosive limit.
