HAZMAT HAZWOPER


Introduction

Lead is used in a variety of operations. While most activities present a minimal risk of exposure, some operations and tasks have the potential to cause significant exposure.

This lead awareness training presents properties and uses of lead and operations and activities with potential lead exposures. Lead, as used in this course and addressed by Occupational Safety and Health Administration (OSHA) lead standards, includes

• elemental lead,

• all inorganic lead compounds, and

• lead soaps (organic lead compounds used as paint additives).

Note: Organic lead compounds other than lead soaps (such as tetraethyl lead, an additive in gasoline) are not covered by OSHA lead standard, but may still pose potential health hazards.

Lead Awareness Training Module Objectives

After completing this module, you will be able to recognize the properties and uses of lead, operations and activities with potential lead exposures, and potential nonoccupational exposures to lead.

Properties of Lead

The properties that make lead useful can also make it dangerous. The following table lists some of the physical and chemical properties of lead that are important to consider when weighing the benefits of using lead against its hazards.

Low Melting Point
Lead has a relatively low melting point, allowing it to be easily formed and cast, but also allowing airborne forms of lead to be generated. Therefore, when working with or around lead, accidental exposure to heat sources, sparks, and other sources of ignition should be avoided.

High Atomic Weight
Lead has a high atomic weight and density that make it useful as a shielding material. However, these properties also make it a heavy metal, and heavy metals are toxic to the human body.

Soluble in Acids
Lead has been used extensively in the past for plumbing because it is insoluble in water and it seals pipe connections well. Unfortunately, lead is soluble in acid, and water may be slightly acidic, causing the release of lead into water systems. Leaded glass containers in which fruit juice, wine, or other acidic liquids have been stored may contain dangerous levels of lead because of this solubility.
