What is a 'Credit Facility'. A credit facility is a type of loan made in a business or corporate finance context, including revolving credit, term loans, committed facilities, letters of credit and most retail credit accounts.
The threshold limit value (TLV) of a chemical substance is a level to which it is believed a worker can be exposed day after day for a working lifetime without adverse health effects. Threshold limit value-Time weighted average (TLV-TWA): average exposure on the basis of a 8h/day, 40h/week work schedule.
OSHA sets limits for the amount of chemicals workers can be exposed to during their work shift. OSHA has the power to enforce these limits. The Permissible Exposure Limit for ammonia set by OSHA is 50 parts per million (ppm) averaged over an eight hour work day. This is the standard that must be met in every work place. For example, this means you can be exposed to 100 ppm for 4 hours of your shift as long as you are not exposed to any ammonia for the other 4 hours of your work day.
