Environment, Health & Safety
Solvents, exotherms and pressure. Everyone goes home at the end of the shift, and the effluent leaving the site is within consent.
API manufacturing is genuinely hazardous work. Flammable solvents in volume, reactions that release heat faster than a jacket can remove it, and materials that are harmful long before they are acutely toxic.
Safety systems that depend on people being careful will fail, because eventually someone will be tired. The systems below are designed to be robust to that.
Preventing the incident
Thermal hazard assessment
Reaction calorimetry before scale-up establishes heat of reaction, adiabatic temperature rise and the time to maximum rate. No uncharacterised exotherm is taken to plant scale.
HAZOP studies
Structured hazard and operability review for new processes and for any significant change to an existing one, with actions tracked to closure before the process runs.
Stop-work authority
Any employee can halt an operation they believe is unsafe, without seeking permission and without consequence. This is a written policy, not an aspiration.
Engineered protection
Relief sizing, rupture discs, interlocks, inerting and emergency quench designed into the plant rather than managed by procedure.
What leaves the site
Effluent treatment
On-site treatment with multiple-effect evaporation, discharging to the estate common facility within consented limits, with monitoring at the outlet.
Emissions control
Scrubbers on process vents, solvent vapour recovery and stack monitoring against consent conditions.
Solvent recovery
Solvents recovered and reused within the process wherever quality permits, reducing both purchase cost and waste volume.
Hazardous waste
Segregated, manifested and consigned only to authorised handlers, with disposal certificates retained.
Greener chemistry
R&D targets solvent substitution and step reduction, which cuts effluent at source rather than treating more of it.
Consumption monitoring
Water, power and solvent consumption tracked per kilogram of product so efficiency is measurable rather than asserted.
Occupational health and preparedness
Exposure control
Containment and local exhaust ventilation as the primary control, with personal protective equipment as the last layer rather than the first.
Health surveillance
Pre-employment and periodic medical examinations appropriate to the materials each role handles, including for contractor staff.
Emergency response
On-site emergency team, fire water system, spill control and an evacuation plan rehearsed through regular drills.
Incident reporting
Near misses are reported and investigated, not just injuries. A site with no near-miss reports has a reporting problem, not a safety record.
