Hi, The reference quoted CFR/OSHA is a good place to look for details and in addition of that for quick reference following areas should be in the list of actions;
1. Risk Assessment / JSA
2. Permit to work.
3. Awareness to possible hazards associated with the scope of job; pyrophoric substances.
4. Atmosphere pre-entry checks with digital multi gas detectors or sometimes by dragger tubes (only when you know exactly what possible vapours can be encountered; mercury
5. One of the most important task is "Responsibilities" of a standby person and his actions, because lives of personnel depending upon him.
6. Also when the spaces are not in use there should be a sign board "Restricted Access", there are some industry reports where even in small heat exchanger person poked in but totally unware with the presence of N2 purging as no sign was dispalyed.
7. Entry & exit control checlist.
8. Rescue Plan and how many personnel are allowed to work inside.......
9. Use of low voltage inside; 50 v.
10. Acoustic noise levels if there is a grinding,....jobs
11. Heat / cold factors, AC units will help to control the temperatures.
Hopefully these details will help you in preparing your tasks.
