Occupational hygiene for beverage manufacturing
Breweries, soft drink bottlers, distilleries, dairies and juice plants run some of the most hazard dense operations in manufacturing, and almost none of those hazards are visible on a plant tour. We measure them.
A beverage plant packs an unusual range of exposures into a single site. Grain dust at intake, radiant heat in the brewhouse, asphyxiating gas in the cellars, crystalline silica in filtration, concentrated chemistry in clean in place, punishing noise on the packaging lines and ammonia in the engine room. Each belongs to a different discipline, and a plant that treats them as one generic safety topic will miss the ones that matter. Our surveys follow the product through the plant and assess each zone on its own terms.
What we find
Four exposures that decide beverage plant risk
Carbon dioxide is the risk that kills
Fermentation, carbonation and CO2 recovery release a gas that is heavier than air, odourless at dangerous concentrations and quietly fills cellars, pits and tank bottoms. It has caused fatalities across the industry, often to a second worker attempting rescue. We monitor it at breathing zone and at low level, and we test whether your fixed detection is actually placed where the gas collects.
The silica exposure most plants never sample
Calcined diatomaceous earth filter aid contains cristobalite, a form of respirable crystalline silica. Dry powder dosing and spent cake removal are recognised high exposure tasks, yet filtration is rarely on a beverage plant's sampling schedule. A plant that has never measured it cannot know whether it has a problem.
Packaging halls are the loudest place most workers go
Fillers, cappers, conveyors and glass on glass contact routinely push packaging lines past 85 dB(A), with impulsive peaks that averaged measurements hide. Noise induced hearing loss is permanent, compensable and entirely preventable, and it is where most beverage plant claims originate.
Clean in place protects the product, not the operator
Caustic, nitric and phosphoric acids, peracetic acid and chlorine based sanitisers are handled every shift, often in areas designed for hygiene rather than ventilation. We assess the airborne and dermal exposure that comes with keeping a plant food safe.

From grain intake to despatch
Select a production zone to see the exposures we assess there, the methods we use and the benchmark each result is judged against.
Stage 01
Raw materials & milling
Grain intake, silo storage and milling generate organic dust long before anything is brewed or bottled.
What we look for
Grain and malt dust
Inhalable and respirable organic dust released at intake, conveying and milling.
Endotoxin and bio-aerosols
Bacterial cell wall components in grain dust, linked to grain fever and airway inflammation.
Respiratory sensitisation
Repeated exposure can drive occupational asthma and allergic rhinitis in mill and intake operators.
Combustible dust
Accumulated fine grain dust presents a deflagration risk in mills, elevators and silos.
Confined space entry
Silos and bins carry engulfment risk and oxygen deficient atmospheres.
How we assess it
- Inhalable and respirable dust monitoring by similar exposure group
- Endotoxin sampling and interpretation
- Local exhaust ventilation performance verification
- Dust housekeeping and accumulation surveys to support the explosion basis of safety
- Confined space atmospheric testing procedures
Assessed against inhalable and respirable dust limits, with grain dust treated as a sensitiser.
Why it matters
Food safe does not mean worker safe
Beverage plants are audited constantly, but almost always for product quality and food safety. A plant can hold an immaculate food safety certification while its packaging operators lose hearing, its filtration team breathes cristobalite and its cellar has no gas detection where the carbon dioxide actually settles. The two systems measure different things, and only one of them protects the person doing the work.
Certified and accredited
Internationally certified hygienists, with every sample analysed at ISO accredited laboratories under documented chain of custody.
Integrated with your systems
Findings written to sit alongside your existing food safety and quality management systems, and to feed ISO 45001 and ISO 14001 programmes.
Regional and on site
Plant surveys across Botswana, Namibia, South Africa and the wider region, scheduled around production so the line keeps running.
Start with a baseline survey
A baseline occupational hygiene survey establishes what your workforce is actually exposed to across every zone, defines similar exposure groups and gives you a defensible starting point for control and surveillance.
