Various Hazards:
1. Hearing Conservation. Basically, if you have to raise your voice to communicate, you need hearing protection. Ask your supervisor.
2. Fall Protection. If your feet are more than four feet off the ground, you need fall protection. This protection will generally be job specific. Ask your supervisor.
3. Personal Protective Equipment. This will vary from job to job. Ask your supervisor what is required.
4. Generic Hazards. Think in terms of what job you are sending the employee to. E.g. in a mill, rings, bracelets, long hair and baggy clothes are dangerous. Is there need for specific footwear, etc.
