Common Situations That Trigger a Sampling Call

If any of these describe your situation — you need sampling, not guesswork.

Concrete cutting or jackhammering

OSHA Table 1 task, initial exposure assessment required.

Abrasive blasting or tuck-pointing

PBZ sampling documents exposure vs. OSHA AL/PEL.

Adjacent demolition in occupied building

Area sampling confirms no silica infiltration into occupied spaces.

OSHA citation or inspection response

Documented record demonstrates compliance level at time of inspection.

Pre-demolition bulk characterization

Silica % content required for exposure assessment before work begins.

Recurring drilling or grinding operations

Quarterly or periodic monitoring for ongoing construction or industrial work.

Any of these match your situation? Fill out a quick inquiry — we’ll respond with the right sampling approach within one business day.
