Sound familiar?
Construction HazCom is harder than general industry. Multi-employer worksites, transient crews, and harsh conditions make compliance a daily challenge.
- Multi-employer jobsite—who owns the SDS binder? Everyone points fingers until the inspector writes the citation.
- Subs show up with chemicals you've never heard of. No SDS, no labels, no training records.
- Paper binder locked in the trailer while the crew is on the 14th floor. OSHA says 'readily accessible'—that's not it.
- Inspector asks for your written HazCom program. You have one… somewhere. Maybe from 2019.
- Language barrier: much of your crew may speak only Spanish. Your SDS are English-only.
How HazComFast works on the jobsite
Four steps, from the first jobsite to the crew's phones.
1. Upload your SDS library
Drag-and-drop SDS PDFs or pull from our 30,000+ chemical database. Auto-indexed by product name, manufacturer, and CAS number.
2. Invite subs via link
Generate a guest link per jobsite. Subcontractors view SDS without an account—no app install, no login. You get a read-confirmation audit trail.
3. Built for low-signal jobsites
Your jobsite's SDS load onto the phone on their own, and the app shows how many are ready (17 of 20, 20 of 20) before the crew heads into a basement or tunnel. A QR code on each container opens its SDS in a browser, with no app and no account.
4. Records on the phone
When the inspector is on site, pull up the written HazCom program, training logs and SDS records on the phone.

- GHS label generator for secondary containers—print from your phone
- Toolbox talk generator with sign-in sheet—done in 2 minutes
- Spanish language support for SDS access and training records
On a shared jobsite, more than one employer can be cited
OSHA's Multi-Employer Citation Policy (OSHA Directive CPL 02-00-124, in effect since December 10, 1999) can cite the employer that created a hazard, the one whose crew is exposed, the one hired to correct it and the general contractor in control of the site, when each fell short of what its role requires. Every employer that brings chemicals onto the site also owes the others its SDS access, precautions and labeling system under 29 CFR 1910.1200(e)(2).

Construction HazCom FAQ
Yes. OSHA 29 CFR 1926.59 extends HazCom to construction. Construction employers must have a written program, SDSs readily accessible, GHS-compliant labels, and employee training—just like general industry under 1910.1200.
29 CFR 1910.1200(e)(2), which applies to construction through 29 CFR 1926.59, puts the duty on the employer who brings the chemical on site: its written program must say how it gives the other employers access to the SDSs, tells them the precautions to take, and tells them the labeling system it uses. Separately, OSHA's Multi-Employer Citation Policy (CPL 02-00-124) can cite a General Contractor as a controlling employer when it fails to exercise reasonable care to prevent and detect violations.
Construction sites have dead zones: basements, tunnels, concrete cores, remote sites. OSHA requires SDS to be readily accessible during each work shift, and a sheet that won't load because there's no signal is not accessible. HazComFast loads your jobsite's SDS onto the phone on their own and shows how many are ready before the crew heads underground. First-aid steps for every product on the jobsite stay on the phone, even in airplane mode.
Yes. Any employer whose workers handle hazardous chemicals must comply with OSHA 1910.1200 (or 1926.59 for construction). Contractors bringing solvents, adhesives, cleaners, or other chemicals onsite need SDS access, labels, and training.
Serious violations: up to $16,550 per violation. Willful or repeated: up to $165,514 per violation. Failure to abate: $16,550 per day. These are the 2026 amounts, unchanged from 2025 (no inflation increase). Per-instance penalties are the discretionary egregious (EEEP) exception, not the default. Multiple citation items in one inspection can stack quickly.
Yes. 29 CFR 1910.1200(g)(8) explicitly allows electronic SDS access if employees have immediate access during their work shift. However, you need a backup for connectivity outages. HazComFast loads your jobsite's SDS onto the phone before the signal drops, and a printed set at a central location covers a dead battery.
