This standard is one of a series of safety standards that have been formulated by the Accredited Standards Committee on Safety in Constru

13、ction and Demolition Operations, A10. It is expected that the standards in the A10 series will find a major application in industry, serving as a guide to contractors, labor, and equipment manufacturers. For the convenience of users, a list of existing and proposed standards in the A10 series for Sa

14、fety Requirements in Construction and Demolition Operations follows. A10.1 Pre-Project fall arrest, restraint, positioning, climbing, descending, rescue, escape and training activities.

In cases of practical difficulty or undue hardship, the responsible authority

19、 may grant exceptions to the literal requirements of this standard or permit the use of other devices or methods, but only when it is clearly evident that personnel and equipment protection is assured. 2.

There are generally three types of carabiners: (i) the automatic or self-locking type (required by this standard) with a self-closing; self-locking gate that remains closed and locked until intentionally unlocked and opened for connection or disconnection; (

28、ii) the manual locking type (not permitted by this standard) with a self-closing gate that must be manually locked by the user and that remains closed and locked until intentionally unlocked and opened by the user for connection or disconnection; or (iii) the non-locking type (not permitted by this

29、standard) with a self-closing gate that cannot be locked. 2.13 Certified Anchorage.
