Compressed Gases - Retraining
Why Here -Had training last three years. Have retraining once a year.
Thank you - for working for the dept. each year
Excellent job, great having experienced people.
LAW -Chemical Hygiene Plan developed from Lab Safety Stand. Requires
Training, why here today. Last year Flammables. This training session concentrates on Compressed Gases u sedin some teaching but mostly research.
Special type of hazard.
The purpose of gas cylinder is to "squeeze down" the space needed to store gases. Works more efficiently but creates a great deal of pressure. That pressure can become dangerous.
Hazards - Booklet - Reviews - Working with Hazardous Materials
1. Pressure - 2500 lbs pressure
2. Equipment and Cylinder related –
3. Temperature - L Nitrogen - 238 degree F, SOP For Liquid Nitrogen - SHOW.
Chemical Hazard Categories -
Inert materials - displaces Oxygen - Nitrogen, Helium -asphyxiation
Toxic - cause adverse health effects - CO, Phosgene
Flammable - fire explosion risk - Hydrogen
Reactive - Corrosive - erode flesh or equipment- Chlorine
Oxidizers - react with flamm/combustibles - Oxygen
Oxygen is not AIR
Cryogenic - COLD - boil off vapor can freeze human tissue.
Materials become brittle
Large vapor volume produced,
1 gal LOX =860 gal O2 gas
USE - Safety glasses, face shield, gloves
Cool dry well ventilated place
Strap into place
Keep safety caps on till connections made
Keep out of direct sunlight
Keep Flammables and Oxidizer apart
Many gases should be kept away from electrical equipment.
Cylinders have identifying labels and stencils
Paint color is not an indicator
Never drag across floor
DO NOT hand roll
Use 4-wheel cart
Caps must be on cylinder
DO NOT ride elevator with cylinder
Use clamps to secure cylinder in place
DO NOT stick objects into cap holes
Regulators - reduces high level of pressure to safe usable level - # For each gas
CGA Fitting - connects to the cylinder valve to allow gas to be withdrawn - male/female
No adapters - use correct fitting
Safety Release Devices - prevent rupture and immediate/violet release of pressure (fire)
Allow for controlled release of material
Suspected gas leak should be reported - Me, office
Any bad condition also should be reported - corroded cylinder, rust etc.
Test for Leaks - cover surface with diluted soap solution - tighten or correct fitting
Read the MSDS -- what to wear, how stored, how to handle properly and safely.
Emergency Procedure - 911, 3333, 3700 EOHS, 3665.
You are the only person who can make the area you work safe as possible.
