What ppm of ammonia is safe?

The NIOSH Recommended Exposure Limit (REL) for ammonia is 25 ppm averaged over an eight-hour work day. NIOSH also says that there should be a Short Term Exposure Limit (STEL) of 35 ppm during any 15 minute period in the day. No worker should be exposed to more than that amount over any 15 minute period.

How hazardous is ammonia?

High levels of ammonia can irritate and burn the skin, mouth, throat, lungs, and eyes. Very high levels of ammonia can damage the lungs or cause death. Workers may be harmed from exposure to ammonia.

What hazard class is ammonia?

Anhydrous Ammonia: (SDS) Safety Data Sheet

HAZARD CLASS: (US Domestic): 2.2 (Non-Flammable Gas. 49 CFR 173.115)
PROPER SHIPPING DESCRIPTION: UN1005, Ammonia, Anhydrous
LABEL / PLACARD: (US Domestic): 2.2, Non-Flammable Gas
IDENTIFICATION NUMBER: UN 1005

What type of hazardous waste is ammonia?

DOT#: UN 1005 ERG Guide #: 125 Hazard Class: 2.3 (Toxic Gases) Non-flammable gas which can ignite and burn with explosive force. Stop the flow of gas or let burn. POISONOUS GASES ARE PRODUCED IN FIRE, including Nitrogen Oxides. CONTAINERS MAY EXPLODE IN FIRE.

What is the STEL for ammonia?

35 ppm
ACGIH: The threshold limit value (TLV) is 25 ppm averaged over an 8-hour workshift and 35 ppm as a STEL (short-term exposure limit).

At what ppm is ammonia flammable?

Ammonia is considered a high health hazard because it is corrosive to the skin, eyes, and lungs. Exposure to 300 parts per million (ppm) is immediately dangerous to life and health. Ammonia is also flammable at concentrations of approximately 15% to 28% by volume in air.

What is considered a high ammonia level?

Ammonia is highly toxic. Blood ammonia levels are usually less than 50 micromoles per liter (micromol /L), but this can vary depending on age. An increase to only 100 micromol /L can lead to changes in consciousness. A blood ammonia level of 200 micromol /L is associated with coma and convulsions.

What level of ammonia is toxic?

Ammonia is highly toxic. Normally blood ammonium concentration is < 50 µmol /L, and an increase to only 100 µmol /L can lead to disturbance of consciousness. A blood ammonium concentration of 200 µmol /L is associated with coma and convulsions.

Is ammonia a hazmat?

Anhydrous ammonia is considered an extremely hazardous substance by the Environmental Protection Agency (EPA) and releases of 100 pounds or more must be reported to the National Response Center (NRC) within 24 hours.
