OSHA Hazards for Construction (1926)
Health Hazards OSHA Hazards for Construction (1926)
3
OSH Act of 1970 The purpose of the OSH Act is to “assure so far as possible every working, man and woman in the nation safe and healthful working conditions and to preserve our human resources.”
4
Routes of Entry Inhalation Absorption Ingestion airborne contaminants
penetration through the skin Ingestion eating drinking
5
OSHA Hierarchy of Control
Engineering controls Work practice controls Administrative controls Personal protective equipment (PPE)
6
Types of Exposure Acute Chronic
Short term period between exposure and onset of symptoms Chronic Long time period between exposure to an agent and the onset of symptoms
7
Exposure Limits Air Contaminants
OSHA Occupational Safety and Health Administration NIOSH National Institute of Occupational Safety and Health ACGIH American Conference of Governmental Industrial Hygienists
8
Exposure Limits Air Contaminants
OSHA PEL, STEL, Ceiling NIOSH TWA, STEL, Ceiling ACGIH
9
Exposure Limits Air Contaminants
TWA takes into account variable exposure through a full shift, 8 hour work day STEL limit of exposure during a short period, 15 minutes CEILING absolute maximum level of exposure not to be exceeded

12
Why Target Crystalline Silica Exposure?

13
Occurrence and Use of Silica
SiO2 - basic component of sand, quartz & granite Quartz - 2nd most common mineral in the earth’s crust Airborne silica is produced by:
14
Occurrence and Use of Silica
Airborne silica is produced by: sandblasting rock drilling foundry work stone cutting drilling quarrying tunneling jack hammering concrete manufacturing demolition asphalt pavement manufacturing

18
Silicosis Prevention Program
Personal air monitoring program Training and information on crystalline silica Availability of air and medical surveillance data to workers Respiratory protection program Source: OSHA SEP
19
Silicosis Prevention Program
