Is 25 ppm ammonia 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.
What level of ammonia causes coma?
100 to 200 µmol/L: anorexia, vomiting, ataxia, irritability, hyperactivity. Above 200 µmol/L: Stage II coma, combative state followed by stupor. Above 300 µmol/L: Stage III coma, responsive only to painful stimuli. Above 500 µmol/L: Elevated intracranial pressure, stage IV coma, decerebrate posturing.
What do you do if you inhale too much ammonia?
Ammonia in the respiratory system: If a worker breathes large amounts of ammonia, move him or her to fresh air immediately. If the worker has stopped breathing, administer artificial respiration. Keep the worker warm and at rest while waiting for medical assistance.
