Objectives • Explain the hazards of lead exposure • Identify potential locations • List PPE may be required • List chronic exposure effects
Lead is considered to the one of the heaviestmetalsand yet soft. Color: bluish-white. Figure 1 Lead ballast from vessel’s keel
Meaningof Lead: metallic lead, all inorganic lead compounds, and organic lead soaps. Figure 2 Lead that is being recycled
Lead was widely used prior to the 1980’sbefore federal regulations minimized or eliminated the use. Figure 3 Hull 134 paint flaking off hull
Reduce lead contamination through engineering controls and safework practices. Figure 4 Worker with lead being recycled
A written complianceprogram will address workplace lead exposure and PPE measures. Figure 5 Lead shielding wiring
Written plans must include the following: • Description where lead is located • Engineering plans to control lead exposure • PEL • Air monitoring • PPE, if required • Plan must be reviewed and updated annually Figure 6 Written plan at gangways
Largest concentrations of lead is located within the painting system of vessels. Figure 7 Paint peeling off overhead in galley area
The exterior coating of the ships have different types of painting systems. Figure 8 Exterior paint on military vessels
Most common primer that is found on vessels is red lead primer. Figure 9 Paint chips on deck after testing completed
The interior of vessels may also have a lead primer or coating. Figure 10 Paint test area inside main deck area
Lead-acid batteries located in the engine room. Figure 11 batteries in a series on deck
Battery charging stations, and engineering spacesthrough out the vessel. Figure 12 Engine room and generator area
Lead has been used in the bilge or keel area for ballasting the vessel. Figure 13 Hull in slip being hauled out
Radiations shields in areas of medical area such as X-Ray compartments or nuclear shields Figure 14 Medical office onboard ship
Lead residue may exist within the ammunition storage areas and gun mounts. Figure 15 Ammunition chart in gun mount
OSHA “Action Level” when an employee is exposed to 30 micrograms per cubic meter of air without a respirator requirements Figure 16 Hot work cutting down the sections
Levels at or below (30 ug/m(3)) is for a period of 8-hour per day working conditions. Figure 17 Workers cutting lead shielded wiring for processing
Respirator required when concentrations of lead of 50 micrograms per cubic meter of air Figure 18 Respirator worn by lead workers outside restricted area
Permissible exposure limit (PEL) (50 ug/m(3)) is an average 8-hour per day. Figure 19 Work area around lead wiring being recycled
Respirator requirements for fit test and training must be documented prior to usage. Figure 20 Respirator and face shield
Initial monitoring determines if an employee is exposed to lead concentrations at or above the action levels. Figure 21 Lead piping and pieces removed from vessel
Personal lead sampling must be collected for a full shift (at least 7 continuous hours). Figure 22 Sorting valves from non-ferrous materials
Monitoring must take place if employee complains of symptoms or displays health issues. Figure 23 Monitoring the workplace for lead residue and products
Long term exposure to lead is increased blood pressure. Figure 24 Worker on forklift moving tote out of warehouse
Memory loss or difficulty in concentrating Figure 25 Worker coming out of engine room on ladder
Joint and muscle pains Figure 26 Cut out for hoisting sectionals
Decreased fertility Figure 27 Working in the area near the propeller shaft
Blood poisoning Figure 28 Cutting sections down on land
There are links to Alzheimer’s disease Figure 29 Sunlight on water of ship
Action Discussion Why is it important to protect yourself from lead exposure?
