Documented collection and testing for employer substance-use policies, worksite-access programs, project timelines, school placements and incident-response procedures.

Testing options include express and laboratory-based drug testing, oral-fluid collection, breath-alcohol testing and chain-of-custody documentation.

Common requests include pre-employment, pre-access, post-incident, reasonable-cause, return-to-duty, follow-up, DOT and non-DOT, and random testing where permitted by law and company policy.

Section 250 of Alberta’s Occupational Health and Safety Code requires employers to ensure that respirators dependent on an effective facial seal are correctly fit tested in accordance with CSA Standard Z94.4-02.

AT Safety Training provides qualitative and quantitative fit testing for N95, half-mask, full-face and SCBA respirators. Workers receive instruction on correct use and seal checks, and completed fit-test records are issued for employer files.

Section 223 of Alberta’s Occupational Health and Safety Code requires employers to provide audiometric testing, at the employer’s expense, for workers who are or may be exposed to excess noise.

Required testing includes an initial baseline test within six months, a second test within 12 months and testing at least every second year afterward.

Testing is completed by registered audiometric technicians, with audiologist review when follow-up is required.

Section 222 of Alberta’s Occupational Health and Safety Code requires hearing protection used at a worksite to meet and be fit tested in accordance with CSA Standard Z94.2-14 (R2019).

Personal Attenuation Rating testing measures the noise reduction an individual worker achieves when earplugs or earmuffs are fitted and worn. Testing is available for a wide range of earplug and earmuff styles and brands.

Spirometry measures airflow and lung capacity. It can establish a baseline and monitor respiratory function for workers exposed to dust, fumes, vapours and other airborne contaminants.

Testing supports occupational health surveillance identified through a workplace hazard assessment, exposure-control program, medical direction or worksite standard.

Pre-employment, respirator and confined-space medical assessments are completed against the documented job demands, worksite standard or medical form provided by the employer.

Medical testing must be related to the duties and demands of the position. The employer retains responsibility for employment decisions and applicable accommodation obligations.
