During heat-treating operations, the metal is subjected to heating or cooling to acquire specific properties from that metal.
Heat-treating operations require a quench as an integral part of this process. Liquid quenches normally involve the use of mineral oils, water-based solutions or molten salt. Less severe quenches use circulated gases or forced air, or involve cooling in still air. Refer to Metalworking Machines - General for basic safety tips.
Quenching operations pose various health and safety hazards to workers. These include exposure to chemicals, working in high temperatures, and the risk of fire or explosion.
Consider the properties of the quenchants plus the design, construction, location, control, monitoring and maintenance of the furnace itself to minimize these risks.
Quenching operations are often followed by a degreasing with chlorinated solvents or water-soluble compounds.
Only operate heat-treating equipment when properly trained.
Add a badge to your website or intranet so your workers can quickly find answers to their health and safety questions.
