How to Limit Your Risk • Use engineering and work practice controls – Substitute materials – Wet methods – Tools & equipment with built-in water systems – Local exhaust ventilation – Specialized tools NYSDOL Public Employee Safety and Health Bureau 21
Engineering Controls –Wet methods –Local exhaust ventilation –Isolation –Specialized tools –Substitute materials NYSDOL Public Employee Safety and Health Bureau 22
Engineering Controls • Wet methods – Hose down materials & surfaces during work – Water mist surfaces or piles of material – Wet-sweep work areas – Clean up before wet material dries NYSDOL Public Employee Safety and Health Bureau 23
Engineering Controls • Local Exhaust Ventilation – Capture dust before it gets into the air – Hoods and other enclosures – Tools, equipment (e. g. sanders, needle guns) with built-in dust collection systems NYSDOL Public Employee Safety and Health Bureau 24
Specialized tools • Longhandled torches NYSDOL Public Employee Safety and Health Bureau 25
Engineering Controls • Substitution – Use lead-free materials, e. g. paint, glazes – Use lower-lead solder NYSDOL Public Employee Safety and Health Bureau 26
Work Practices Park your car away from dusty areas • Store personal belongings away from dusty areas • NYSDOL Public Employee Safety and Health Bureau 27
Work Practices • Don’t smoke! • Don’t eat, drink, chew gum or tobacco, apply lip balm or handle contact lenses in a lead area NYSDOL Public Employee Safety and Health Bureau 28

Work Practices • Don’t Dry Sweep • Don’t “dump” materials, objects. • Stand back. Keep your face out of the dust cloud. • Stand upwind of the work. NYSDOL Public Employee Safety and Health Bureau 30
Work Practices • Vacuum clothes frequently. • Shower and change clothes before leaving worksite. NYSDOL Public Employee Safety and Health Bureau 31
Work Practices • Housekeeping – Remove dust BEFORE it’s airborne – Vacuum with HEPA filters – Clean up slurries while still wet – Keep dust control systems in good repair NYSDOL Public Employee Safety and Health Bureau 32
