NCHRP Project 14-30 59 5.0 WORKER SAFETY AND COMPLIANCE WITH ENVIRONMENTAL REGULATIONS 5.1 Worker Safety OSHA Regulations Workers involved in spot painting must take special precautions to protect themselves from hazards associated with painting operations. That is addressed under the Occupational Safety and Health (OSH)

From page 60... ...
NCHRP Project 14-30 60 applies to a hazard. Worker safety and health requirements are addressed from an owner/contractor/ subcontractor perspective in SSPC PA 10, "Guide to Safety and Health Requirements for Industrial Painting Projects." That document refers to OSHA Compliance Directive CPL 02-00124, which addresses citation policies for multi-employer worksites.

NCHRP Project 14-30 61 industrial painting operations that require OSHA-defined competent persons applicable to construction. Some of those are related to general activities performed by highway agency crews and may not require additional competent personnel outside of those specific to bridge painting.

NCHRP Project 14-30 63 Respiratory Protection Respiratory protection is an important factor for workers involved in maintenance-painting activities. Workers cleaning bridges can be exposed to lead disturbed by the cleaning processes and histoplasmosis from bird droppings.

From page 64... ...
NCHRP Project 14-30 64 The use of vacuum-shrouded power tools reduces the worker exposure to respirable lead but some level of personal monitoring is required to establish exposure levels. Experience has shown that hand/power tool surface preparation have had minimal environmental impacts beyond the need to dispose of lead paint debris as a hazardous waste and that worker safety and health requirements have been typically limited to half-face respirators.

NCHRP Project 14-30 65 5.2 Environmental Compliance Wastes generated during spot painting can include: • Wastewater from washing operations • Airborne particulates from surface preparation operations • Miscellaneous solid wastes from cleaning operations • Spent solvents and coatings/ containers • Paint chips • Related debris from surface preparation and painting (e.g. rags, tarps, brushes and rollers)
|
From page 66... ...
NCHRP Project 14-30 66 • Water blasting/water jetting (with or without abrasives) • Chemical stripping The first two methods are more likely to be used on bridges except for vacuum blasting, which has rarely been used.

From page 67... ...
NCHRP Project 14-30 67 environmental division personnel if in-house forces were involved. Unlike abrasive blasting, hand tools and power tools with vacuums shrouds typically do not pose significant air emission problems and can be used safely in most environments with a minimum level of containment (ground cloths and wind screens or bibs)
|
From page 68... ...
NCHRP Project 14-30 68 paint can be left in open containers until it has solidified and is disposed of as a non-hazardous waste. For small quantities of hazardous wastes, the agency can cooperate with the state DNR to develop a suitable guide for collecting, storing, transporting and disposing of hazardous waste.

From page 69... ...
NCHRP Project 14-30 69 cartridges, and disposal clothing can be stored in sealed impermeable bags or other sealed containers and labelled as a lead-containing waste (depending on the concentration of lead in the coating)

From page 70... ...
NCHRP Project 14-30 70 categories of waste generators and different requirements from those of the US EPA. Hazardous waste needs to be permitted, manifested, and delivered to TSD facilities by licensed hazardous waste transporters.
