When the operation of a machine or accidental contact with it can injure the operator or others in the vicinity, the hazards must be either controlled or eliminated.

Crushed hands and arms, severed fingers, blindness the list of possible machinery-related injuries is as long as it is horrifying.
There seem to be as many hazards created by moving machine parts as there are types of machines.
• Avoid wearing jewelry.
Machine Maintenance Checklist for Safety:
Keep machines repaired, lubricated and adjusted.
Clean up excess lubricants.
Clearly mark control switches and valves that control machines.
Incorporate Safeguarding Technologies
Primary
Eliminate and Reduce Hazards by Design
Where to begin
• Know how to use the machine safely before operating. • Have you reviewed the owner's manual? It will provide
Identify Equipment Hazards and Task Hazards
Estimate Risk & Probability
Determine Whether Risk Is Tolerable
If Untolerable, Risk Reduction Measureseguards are essential for protecting workers from needless and preventable injuries.
A good rule to remember is:
Any machine part, function, or process which many cause injury must be safeguarded.
operating, repairing, lubricating and fuel information. • Are the Warning Decals in place? • Are the machine guards properly placed and in good condition? • Are electrical lines damage free? • Are air and hydraulic lines in good condition and not leaking? • Is the setup a proper setup? • Is the area around the machines orderly?
Risk Assessment Process
Gather Equipment Specifications
Determine Equipment Limitations
Catastrophic: Permanent Disabling Serious: Severe Disabling
Moderate: Significant Disabling Minor: Sligh Disabling Very Likely to Occur Likely, May Occur Unlikely, Not Likely to Occur Remote: Very Unlikely
Safety begins before you even start the equipment!
Personal Protection:
• Wear PPE, such as goggles, safety shoes and leather gloves.
• Long hair should be tied back or tucked under to avoid getting caught in machinery.
Tolerable Risk: "risk that is accepted for a given task and
hazard combination"
- as described in ANSI B11.TR3
Following an organized and logical approach, risk assessment and risk reduction can achieve a tolerable risk.
