10-10 Safety Messages VX30/VX50 Gen3/ECO50 Vacuum Excavators
CRYSTALLINE SILICA
Breathing crystalline silica dust over time can cause silicosis, a disabling, non-reversible, and sometimes fatal
disease of the lungs. United States Federal OSHA has established exposure limits for employees. Avoid
exposure to dust containing crystalline silica in excess of these limits.
Crystalline silica is a basic component of sand, rock, concr
ete, brick, block and mortar. Many activities at
construction sites such as breaking, chipping, drilling, cutting, etc., produce dust containing crystalline silica.
Air monitoring may be necessary to determine whether jobsite conditions expose workers to excessive levels of
crystalline silica dust. Depending upon air monitoring results, the following measures may be necessary to avoid
exposure to excessive levels of crystalline silica dust:
• Perform
an Exposure Assessment.
• Crea
te a written Exposure Control Plan.
• Ho
usekeeping
• Medical surveillance
• Employee
training
WARNING: Breathing crystalline silica puts workers at increased risk of developing
serious silica-related diseases including: silicosis, lung cancer, kidney disease, Chronic
Obstructive Pulmonary Disease (COPD). Death or serious illness could result. Avoid
exposure to crystalline silica dust according to OSHA guideline 29 CFR 1926.1153.
