A breath analyzer is only as effective as the policy behind it. The most common reason workplace alcohol programs get challenged isn't faulty hardware — it's an unclear, inconsistently applied policy.
A defensible pre-shift screening policy spells out who is tested, when, on what device, and what happens after a positive result. It should require a confirmatory second test, document calibration history, and protect the dignity of the worker throughout. Random and post-incident testing should follow the same documented chain.
Pair the policy with the right equipment tier: a fixed wall-mount station for high-traffic gates, a rugged handheld for supervisors, and a clear escalation path to an evidential fuel cell device when a result needs to stand up to scrutiny. Get the policy and the instrument right together, and the program protects both your people and your organisation.
