m ' HVS or Toxic Gas Exposure Ã
Ã
Ã
Ã
Hydrogen Sulfide ƛ characterized by an odor of rotten eggs. A very small concentration can be fatal. When encountered, employees must wear approved type masks when their work requires them to be exposed to the gas, in any way. Hydrogen Sulfide is highly toxic, colorless, and heavier than air. It has the odor of rotten eggs, initially. The only positive means is by testing with an approved HVS detector.
Ã
It forms an explosive mixture with air. The LEL is £.0 The UEL is £ÿ. |
p
m ' HVS or Toxic Gas Exposure General rocedures Any area where HVS has been reported or encountered, or where there is insufficient oxygen, there should be NO entry until sufficient tests have been made to determine the extent of the hazard and the area is purged to reduce the hazard to allowable concentrations. Ã
For Toxic atmospheres, the employer should require proper respiratory equipment to be used by a trained employee, required to enter the area. Ã
Employees required to enter should be required to wear a safety harness with tail line for emergency retrieval.
Ã
A rescue watch(buddy), stationed outside of the hazard area with proper rescue equipment is also required to assist in case of emergency. Ã
Ã
Canister-type filter masks should not be used.
Employees should be required to wear self contained respirators (SCBA) in those atmospheres where tests indicated oxygen content is less than necessary to sustain life.
Ã
V
p
m ' HVS or Toxic Gas Exposure All employees should be trained and periodically refreshed in the use and operation of breathing equipment available on the job. Ã
Medical personnel readily available for consult on matters of occupational health. Emergency numbers should be conspicuously posted. Ã At least one employee, if not more, per shift trained in |st aid and CPR, and be on-site. Ã Where harmful chemicals are being used, readily accessible facilities should be available for rapid flushing of the eyes and/or skin areas. Ã
NEVER FORGET THAT HYDROGEN SULPHIDE IS A DEADLY GAS.
