Hazardous Paint and Lead Paint
According to AS4361.1 – 2017, hazardous paint is a dry paint containing ingredients that have the potential to create human health risk, toxic workplace atmospheres, hazardous wastes and pollution if disturbed or eroded.
NOTE: Toxic ingredients of paints include lead, chromates, arsenic, cadmium, asbestos, and coal tar derivatives such as phenols or polycyclic aromatic hydrocarbons.
Lead paint is defined by the superseded AS 4361.1:1995 Guide to Lead Paint Management-Industrial Applications as paint containing in excess of 1% by weight of lead. This definition is also used in the National Code of Practice for the Control and Safe Use of Inorganic Lead at Work [NOHSC: 2015 (1994)]. The National Health and Medical Research Council (NHMRC) Standard for the Uniform Scheduling of Drugs and Poisons (SUSDP) limited the lead concentration in paint to 1% by 1970, 0.5% in 1990, 0.25% in 1992 and 0.1% in 1997.
Hazardous Paint Compliance Plan (HPCP)
A document prepared by the contractor performing the hazardous paint removal giving a detailed description of engineering controls, work practices and safety precautions that will be adopted for the execution of the work.
Threshold Concentration Criteria for Hazardous Paint Projects
The total quantity (mass) of hazardous paint will influence the level of potential emissions and the nature and quantity of waste produced. The greater the quantity of paint, the higher the risk of emissions will be for a given removal strategy.
According to AS4361.1 – 2017, the suggested hazard threshold concentration criteria for determining if a project poses a significant hazard are presented in Table 1.
