These standards require that compressed and liquid gas cylinders be safely secured. These cylinders are also required to be marked as to their contents, placed in specified storage areas, and protected from falling material, contact with power lines, energized electrical equipment, exposure to flammable liquids, and excessive heat (coal). Cylinders are not to be stored or left inby the last open crosscut and, when not in use, the cylinder valves will be closed and the hoses removed (coal).

Issues to Consider in Determining Compliance:
• Are compressed and liquid gas cylinders secured to prevent accidental tipping or falling?
• Do persons work or travel in the area where the bottles are stored?
» Could persons in the area be affected if a bottle was to tip or fall and explode or discharge its contents?
