General Warnings And Notifications / Set Construction Safety

General Warnings and Notifications

California Prop 65 requires businesses to give a “clear and reasonable warning” prior to exposing any person to a detectable amount of a chemical listed by the state as covered by the Prop 65 Statute.

The list contains a wide range of chemicals. Many of them are ingredients or components of common household products, such as ceramic ware, alcoholic beverages and aspirin. Others may be byproducts of certain combustion processes, such as motor vehicle exhaust, tobacco smoke and burning natural gas. Still others may be chemical- containing products such as dyes, or specialty pigments.

Therefore, as required by the CA Prop 65 Statute, the following Prop 65 Warning is provided:

WARNING: This facility contains chemicals known to the State of California to cause cancer and birth defects or other reproductive harm.


Both state and federal law require building owners to notify occupants of the presence of any asbestos-containing materials (ACM) in buildings in which they work. We are making this notification to comply with these laws, and because it is Warner Bros. Studios policy to make such information available.


Asbestos-containing materials were commonly used in the construction of buildings and homes prior to 1979. ACM were once used as part of certain building materials, such as insulation, roofing materials, floor tiles, and spray-on insulation.

Warner Bros. Studio has a comprehensive Operation and Maintenance Plan for Asbestos Containing Materials. Under this plan, we use licensed ACM abatement firms to remove ACM from mechanical rooms and exposed pipes and ducts; and to remove any ACM present prior to or discovered while doing Studio remodeling and renovation work. In addition, we have conducted air sampling in all WB buildings known to contain ACM. The Environmental Protection Agency (EPA) and The Occupational Safety & Health Administration (OSHA) set standards for building occupancy, and we are pleased to say that all WBSO buildings meet these standards.

The following WBSO buildings are known to contain ACM and are subject to this notification: 4, 5, 8, 10, 11, 12, 13, 15, 18, 19, 22, 27, 31, 34, 35, 37, 41, 44, 51, 52, 53, 54, 55, 56, 58, 59, 66, 67, 68, 69, 71, 76, 81, 90, 95, 131, 133, 135, 137, 138, 139, 140, 142, 143, 146, 151, 154, 155 and 3R.

The survey reports and bulk sample and air sample test reports for particular building locations are available for inspection by appointment. Because inhalation of unprotected airborne asbestos fibers may pose serious potential health risks, it is important that you not disturb potential ACM (i.e., by drilling, sanding or hammering) without first calling S&EA at 818-954-2890 to receive clearance.

WB Productions – Specialized Safety Equipment / Personal Protective Equipment (PPE)

Safety & Environmental Affairs (S&EA) maintains a variety of specialized safety equipment that is available for use by WB employees.  S&EA’s safety-related equipment inventory includes items like face shields, hearing protection, fall protection equipment, horizontal safety lines, vertical rope grabs, Nomex clothing (coveralls, gloves, and hoods), airline respirators, potential confined space ventilators, and high-velocity ducted air machines.  Disposable of personal protective equipment (PPE) is provided to individual employees free-of charge to protect them in a variety of work conditions.  Other more expensive and specialized equipment is provided for your departments and production companies free of charge; however, lost or abused equipment will be charged to the production.

Fall protection is mandatory when working in situations that expose employees to potential falls greater than 4 feet in height and where guardrails are absent.  Some examples: outside of the catwalks in the permanents of a soundstage; on roofs, shooting platforms or decks built for set construction.

When larger quantities of items are required, such as for an entire crew, disposable items such as safety glasses, dust masks, earplugs, gloves, and goggles, and other PPE items are available for purchase through the WBSO Paint Department (818) 954-4444, or VER Sales (818) 567-3000.  In addition, S&EA maintains a limited supply of expendable safety equipment to be used in emergency scenarios.

Please call S&EA with any questions or concerns at (818) 954-2890.

Third Party Productions – Personal Protective Equipment

Productions unaffiliated with WB or its production entities who are leasing production space from WBSO are responsible to supply their employees with Personal Protective Equipment as required by Cal/OSHA. Please call S&EA (818) 954-2890 for specific requirements. This equipment can be purchased or rented from VER Sales in Burbank (818) 567-3000.
