What term is used to describe the objects mentioned that are relevant for lifting in hazardous environments?

The term "snatch blocks" refers to specific equipment used in lifting operations, particularly in hazardous environments. Snatch blocks are designed to change the direction of the pull of a cable or rope and can effectively increase lifting capacity by allowing the user to create mechanical advantage. They are particularly useful when dealing with heavy loads or in situations where direct lifting is challenging due to space constraints or safety concerns.

While chains, slings, and pulleys are all critical components in lifting operations, they serve different purposes. Chains are typically used for securing loads or connecting lifting equipment, slings are flexible lifting devices made from fabric or chains that support loads, and pulleys facilitate lifting by changing the direction of force or increasing the lifting capability through systems of multiple pulleys. In contrast, snatch blocks specifically allow for easier manipulation and control of the lifting angle and load, making them essential in hazardous environments where precision and safety are paramount.
