Post-accident testing supplies, stocked where the incident happens.

OSHA's guidance is that blanket "every recordable incident triggers a test" policies are not automatically retaliatory, as long as the testing covers substances that could plausibly have contributed to the incident. The retaliation risk comes from selective enforcement, such as testing the worker but not the supervisor, or testing only after worker-reported injuries but never after equipment-failure injuries. Keep documentation consistent across your workforce to support a defensible policy.

Two models. (1) Subs must have their own program and present prequal evidence, since most ENR GCs require this through ISN/Avetta with documented annual testing rates. (2) GC supplies its program as a project requirement and bills the sub via change order. ASC supports both. We provide a documentation packet subs hand to ISN/Avetta. For Model 2, we can issue per-project sub-billing under a master GC subscription.

Job site state generally determines the testing policy. A worker hired in a state with different off-duty use protections, then deployed to a job site in another state, is typically tested under that job site's policy, since the work-site rule generally controls rather than the residence rule. Our subscription kits ship to job-site addresses with state-specific policy reminders for the safety officer. Cross-border travel work for highway or utility crews is the exception; we configure separately for those.

Many states offer workers' comp premium credits for employers with a qualifying drug-free workplace program, though the exact class codes, discount amounts, and requirements vary by state and carrier. The typical qualification path includes a written policy, supervisor training, a full testing program (pre-employment, post-accident, random, and reasonable-suspicion), an EAP referral, and a documented annual program audit. ASC's subscription generates the audit documentation; your insurance broker handles the carrier filing.

For post-fatality and high-litigation-risk incidents, split-specimen collection is the standard of care. The collector splits the specimen into two sealed bottles labeled A and B. Bottle A goes to confirmation; Bottle B is held at the lab for retest if the worker contests. ASC's post-accident kits include split-specimen bottles and chain-of-custody documentation. For routine post-accidents, single-specimen is typical; for fatalities or serious injuries, split-specimen is the safer standard.

Collective bargaining agreements typically negotiate specifics: panel composition, MRO selection, notice periods, return-to-work conditions. The CBA controls within its members; the GC's policy controls for non-union crews on the same site. We configure separate panels per union when the CBA mandates it. For mixed crews, the safety officer maintains two policy binders. Verify any new program with the local business agent before standing it up, since the grievance cost of skipping that step can exceed the testing-program savings.

Care first, test second. Once the worker is medically stable, the ED can perform the post-accident draw under the GC's standing order. ASC supplies are not used in ED-administered tests, since the hospital uses its own lab workflow, but the result is sent back to the employer's MRO for adjudication. For tests run at the trailer before ED transport (minor injuries), our chain-of-custody form includes a transport-after-collection field for the timestamp.

Workers can refuse, but refusal is generally treated as a positive result and can lead to termination or loss of future employment opportunities.
