Professional fuel cell breath alcohol analyser for workplace pre-shift safety screening — accurate BAC measurement for industrial sites, construction projects, and vehicle operators across NE India.
A workplace alcohol tester, also called a breath analyser or breathalyser, is an electronic instrument that measures the concentration of alcohol vapour in a person's exhaled breath and converts it to a blood alcohol concentration (BAC) equivalent reading. It is used by employers, safety officers, and site managers to screen workers and drivers for alcohol consumption before they commence safety-critical tasks — operating heavy machinery, driving vehicles, working at height, handling hazardous chemicals, or entering confined spaces.
Multi Trade Combines stocks professional workplace breath alcohol testers at our Guwahati counter for industries and contractors across Northeast India. In Assam's oil and gas sector (ONGC and OIL operations in Jorhat, Sibsagar, and Dibrugarh), hydroelectric construction projects in Arunachal Pradesh, and large civil contracts under NHIDCL and NHAI in the Northeast, pre-shift alcohol testing of workers and drivers is a mandatory part of HSSE compliance and site access control. A positive test result stops a potentially fatal accident before it happens.
Construction and infrastructure contractors working under internationally specified HSSE standards are the primary users. EPC contractors on power transmission and oil pipeline projects in Assam and Arunachal Pradesh conduct daily pre-shift gate testing of all workers and vehicle operators as part of their safety management system. Tea estates conduct alcohol testing of tractor and truck drivers who operate on estate internal roads and on public roads during plucking and transport seasons.
Industrial facilities with process safety requirements — fertiliser plants, LPG bottling plants, and petrochemical storage terminals in and around Guwahati — use alcohol testers as part of their permit-to-work systems. A positive alcohol test cancels a hot work or confined space entry permit. Public transport operators, school bus operators, and logistics companies subject to CMVR enforcement also use breath testers for driver checks.
The alcohol tester pairs with personal protective equipment, site access control barriers, and safety signage — all available in the Safety Equipment section from Multi Trade Combines, Guwahati. Shipped directly from Guwahati to sites across Northeast India.

Professional-grade workplace breath alcohol testers use electrochemical fuel cell sensors (the same technology as police-grade breathalysers) and are accurate to within ±0.005 BAC (blood alcohol content equivalent) when correctly calibrated. For workplace safety compliance purposes — gate entry checks, pre-shift safety verification, and random screening — this accuracy is sufficient and accepted under Indian occupational safety guidelines and industry safety management systems. Fuel cell-based units require periodic calibration (typically every 6 to 12 months) to maintain accuracy. Semiconductor-type testers are cheaper but less accurate and not suitable for formal compliance screening. Always specify fuel cell for safety-critical workplace applications.
An effective workplace alcohol testing programme in a Northeast India industrial setting starts with a written policy specifying the BAC limit (most Indian industries adopt 0.02% or zero tolerance for safety-critical roles), the testing frequency (pre-shift, random, post-incident), and consequences of a positive test. All employees and contractors must be briefed and sign the policy. The tester should be operated by a trained person, and the test procedure must be documented. For sites following IS 45001 or client-specified HSSE standards — common on oil & gas projects in Assam, hydroelectric projects in Arunachal Pradesh, and airport construction contracts — documentary evidence of testing is required.
