SAFETY INSTRUCTIONS
Review and completely understand the operating and safety instructions before using this unit.
WARNING!
The calcium carbide reagent used with this test must be handled with great care. When
exposed to water, calcium carbide produces highly ammable or explosive acetylene gas.
• Users must understand and follow local regulations and calcium carbide Material Safety Data Sheet
(MSDS) guidelines and procedures regarding transportation, storage, handling and disposal.
• Users of this apparatus must read and understand the operating instructions in this manual.
• Testing must not be performed in confined spaces or in the vicinity of an open flame, lighted
cigarettes, embers or any other potential source of ignition.
• When releasing the gas from the apparatus, take care to direct it away from the face and body.
• Care should be taken not to store, dispose of, or place the calcium carbide reagent where it may
come into contact with water, because it will produce explosive acetylene gas.
• Any application not specically covered in this manual will be considered improper use and will
void the warranty.
• Testing excessively wet material, adding water to the testing chamber, or improper use of the
equipment could cause pressures to exceed the safe level for the apparatus. This may damage
the device and create an unsafe condition for the operator.
• Long sleeves, gloves, eye protection and dust masks should be worn when performing this test.
