Health sampling
ⓘ A sample is a point in time compliance measurement, not an individual exposure history. These figures describe MSHA sampling records and do not establish causation or personal dose.

Metal and nonmetal contaminants (personal samples)
ⓘ Many samples are screening measurements of substances with no applicable exposure limit; they are counted as samples but excluded from every over-limit figure. Over-limit shares use only limit-tested samples.

Employee was welding on a grizzly and took EE's lunch break. EE believes when EE took EE's welding hood and glasses off to wipe EE's forehead EE may have pushed a foreign body into EE's eye. It did not bother EE until late afternoon. On Saturday EE went in and had it removed and was provided an ointment to prevent infection.
