a)      Gas = 100 percent chlorine , a greenish yellow gas, highly toxic, it comes in 100 or 150 pound cylinders, one ton cylinders, and Rail Tankers to 90 tons.

b)      Calcium Hypochlorite = Granular and tablet form 65 to 75 percent chlorine.

c)      Sodium Hypochlorite = Bleach, industrial strength varies by manufacturer, usually 10-12 percent chlorine.

    It is detectable at .08 ppm in the air.

     It is dangerous for long term exposure a 5 ppm in air.

    It is lethal at 1000 ppm in air.

      When changing a gas cylinder for chlorine it is important to use proper safety equipment and to never work alone.

1)      Repair kits are available for chlorine cylinders:

a)      “A” kit for 100 and 150 pound cylinders

b)      “B” kit for one ton cylinders

c)      “C” kit is for rail cars.

There are two valves on a one ton cylinder, they sholud be aligned perpendicular  to the ground.

↑      top valve

↓ bottom vlave

↔          ground

Chlorine liduid will expand at a rate of 460 to 1.

This means that 1 cc of liquid will expand to 460 cc of gas.

Chlorine cylindersa are equipt with fusible plugs to keep the cylinder from rupturing if exposed to  high heat.

At what temperature will the plugs melt?

       All cylinders are equipped with fusible plugs that will melt at 158^oF to 165^oF  to

prevent the tank from rupturing.

      To check for chlorine leaks ammonia is used, a small amount of ammonia vapor is squeezed near the valve and fittings, if a white cloud appears then there is a chlorine leak.

MSDS- MATERIAL SAFETY DATA SHEET

These sheets are part of your "Right to Know" and should be kept on file with access for all workers.

These sheet define the chemicals used in the plant and the dangers and safe handling associated with them.

Lock Out / Tag Out refers to a system used  to make sure that a piece of machinery or a motor or a chemical, water, or steam line, is isolated and denergized for repair, maintenace, or inspection.

The system has very specific protocols involving who can lock out  a piece of equipment and what needs to be done before the lock and or tag can be removed.

PPE - Personal Protective Equipment-

This is the safety equipment provided to and or assigned to an individual. This includes but is not limited to gloves, safety glasses, rain suits, boots, and hard hats.

Remember that this equipment is your responsibility and you must ensure that it is kept in working order and that it is replaced when not in working order.
