Chemical hazards with salts

SAFETY PROFILE Poison by intraperitoneal route. Moderately toxic by ingestion. Mutation data reported. A very dangerous fire hazard when exposed to heat, flame, or by chemical reaction with oxidizers. A severe explosion hazard when shocked or exposed to heat or flame. It is about as powerful as TNT. It is normally mixed with coUoided nitrocellulose or ammonium nitrate and paraffin wax. Can react vigorously with oxidizing materials and the derivatives can be explosive. The mercury and silver salts and other derivatives are much more impact-sensitive. When heated to decomposition it emits highly toxic fumes of NOx. See also NITRO COMPOUNDS.

Chemical extraction or leaching in hazardous waste treatment is the removal of a hazardous constituent by chemical reaction with an extractant in solution. Poorly soluble heavy metal salts can be extracted by reaction of the salt anions with H" ", as illustrated by the following reaction ... 

The Polyquats or polymerized quaternary salt. If we study the list of algicides approved by the DETR Committee on pages 107 and 108 in the book Swimming Pool Water published by the Pool water treatment Advisory group, we observe the Polyquats WSCP (or BUSAN 77), WSCP-2 (or BUSAN 79) and APCA (or BUSAN 1055) and their impact on Hazard and Incompatibility data . Indeed, these quats have a very low toxicity and are compatible with most swimming pool chemicals used. 

After the flushing and visual checking is finished, the equipment is tested under simulated conditions. Again, safe fluids such as air, water, and steam are used wherever possible. Sometimes inexpensive compounds with similar boiling points to the process chemicals are used to check distillation or other separative steps. For solids-handling equipment sometimes salt, the actual raw material, or product purchased for this test may be used. The purpose of these tests is to see whether every piece of equipment performs properly before more expensive and possibly more hazardous process compounds are charged to the system. It also gives the... 

Salt baths can also be applied to mould cleaning. They are efficient in use but have the hazards associated with high temperature caustic chemicals.
