100 deg. F. and below
What is Flash point for combustible materials
What is Flash point for flammable materials
The lower the flash point the more dangerous (fire)
100
SDS
What is the Safety Data Sheet formally known as the material safety data sheets, now in a globally standardized format which contains the health assessment for a particular item. How to safely handle, protection required, what to do in case of an exposure

UEL/LEL
What is Upper explosive limit / lower explosive limit
Will not burn or explode below the lower or above the upper, not enough oxygen above the upper to burn or support life.
200
PEL / TLV
What is the exposure limits established by OSHA and the ACGIH. PEL is OSHA's standard and the TLV is the AGCIH's.
OSHA states that most won't be permanently harmed at it's levels while the ACGIH states that no one will be harmed. MN uses the ACGIH levels
