We evaluate the safety of Laboratory Equipment by applying the IEC/EN/UL 61010-1 safety standard. For equipment that has accessable moving parts, such as sample loaders, we apply section 7.3 "Moving Parts". Under 7.3.4, it states,
- " The physical levels specified below are *not considered to be hazardous.*" - " The maximum tolerable continuous contact pressure is 50 N/cm2 , with a maximum force of 150 N. So for continuous contact pressures greater than 50 N/cm2, we have to apply the Risk Assessment in section 7.3.3. The First step in the Risk Assessment is to define the Severity of the hazard or injury. You have two choices; Moderate and Serious. The standard does attempt to define the potential injury, but this is very subjective. How do you test for a dismembered body part? My Engineers want numbers, not guesswork. I was hoping there are numbers, such as a Contact Pressure that would draw a line between Moderate and Serious. For pinch, crush, and maybe shear hazards, there should be a way to come up with a N/cm2 number or test that can make this determination. Are there such numbers, rules of thumb, industry standards, that would better define the difference? Having something like this would really help.
