What is a safety data sheet (SDS) in construction?

A safety data sheet (SDS) is a standardized document from the manufacturer or importer of a hazardous chemical that explains its hazards, safe handling, protective equipment, and emergency steps. OSHA requires employers to keep them accessible to workers.

A safety data sheet is the instruction sheet for a hazardous product. Every hazardous chemical a contractor brings on site, from concrete form release and PVC cement to spray foam, sealants, fuel, and cleaners, should come with one. The SDS tells workers what the product can do to them, how to store and use it, what PPE to wear, and what to do in a spill, fire, or exposure. They used to be called material safety data sheets (MSDS).

SDSs are part of OSHA's Hazard Communication Standard, 29 CFR 1910.1200. For construction, 29 CFR 1926.59 states that its requirements are identical to those in 1910.1200, so the same rules apply on the job site.

The 16 sections of an SDS

OSHA requires a consistent 16-section format, so a worker can find the same information in the same place on any sheet.

What employers have to do

The employer must keep an SDS for each hazardous chemical in the workplace and make sure the sheets are readily accessible during each work shift to employees when they are in their work areas. On a construction site that usually means a binder in the job trailer or gang box, or electronic access that works on site without barriers. The standard also covers multi-employer sites, such as a GC's job with a dozen subs, where employers need to share information about the hazardous chemicals their workers may be exposed to.

How it works on a real job

Say a flooring sub is installing epoxy coating in a warehouse while an electrical crew pulls wire nearby. The flooring sub's foreman keeps SDSs for the resin, hardener, and primer in the site binder. At the morning coordination meeting, the GC's super reviews the SDS sections on ventilation and PPE and decides the electricians move to the other end of the building during application. Later a worker gets hardener on his forearm. The foreman opens section 4 for first aid steps instead of guessing.

Common SDS gaps on job sites

  • Binder in the office, not on site. Sheets must be accessible where the work happens.
  • Products bought at the store on the way in. The foreman grabbed a new adhesive, and nobody added its SDS.
  • Subs not sharing. Each employer is responsible for its own chemicals, but everyone nearby can be exposed.
  • Outdated sheets. Manufacturers revise SDSs. Section 16 shows the revision date.
  • No training. Having the sheet is not the same as workers knowing how to read it. Cover it in toolbox talks.

SDSs tie to the OSHA 300 log when an exposure becomes a recordable injury, to submittals for product approval, and to your site safety plan. Smart Business Automator stores job documents like SDSs with each project and its subcontractors, so the field can pull them up on a phone.

Frequently asked questions

Is an SDS the same as an MSDS?

Yes, in purpose. MSDS is the older name. Under OSHA's current Hazard Communication Standard, sheets follow the standardized 16-section SDS format.

Who writes the safety data sheet?

The chemical manufacturer, importer, or distributor provides it. The contractor's job is to obtain it, keep it accessible, and train workers on it.

Can SDSs be kept electronically on a job site?

Electronic access can work as long as workers can actually reach the sheets during their shift without barriers. If the site has no reliable signal or devices, keep paper copies.

Which OSHA standard covers SDSs in construction?

29 CFR 1926.59, which states that its requirements are identical to the general industry Hazard Communication Standard at 29 CFR 1910.1200.
