Overview¶

Personal protective equipment (PPE) in a coffee roastery refers to the wearable protective items that reduce operator exposure to the physical hazards of the roasting environment — principally thermal burns, respiratory exposure to smoke and VOCs, eye injury from hot particles or steam, and hearing damage from equipment noise. PPE does not eliminate hazards; it reduces the consequence of exposure when other controls (engineering, procedural) have been applied and a residual risk remains. The appropriate selection of roastery PPE is informed by a hazard assessment of the specific roaster, facility, and task.

Thermal and Burn Protection¶

Heat-resistant gloves: The most important item of PPE in most roastery environments: - Long-cuffed leather or Kevlar gloves rated for contact with surfaces up to 250–300°C - Required when operating the cooling tray immediately after drop, pulling samples, and cleaning hot roaster surfaces after a session - Thin examination gloves or silicone oven mitts are inadequate for roaster use; full leather or Kevlar is the standard

Footwear: Closed-toe, leather or heat-resistant upper construction: - Protects against hot bean spillage at drop and from the cooling tray - Steel-toed boots are not required in most roastery contexts but improve protection in high-volume operations where heavy equipment handling is routine - Open-toe shoes and synthetic-soled footwear are inappropriate

Clothing: Long-sleeved natural fibre garments: - Cotton or wool preferred; synthetic fibres (polyester, nylon) melt against skin in burn contact - Loose-fitting clothing that does not trail near the roaster, drum shaft, or rotating components - Aprons in natural fibres may provide additional protection for operators working closely with the cooling tray

Eye and Face Protection¶

Safety glasses: Minimum standard for all roastery personnel during active roasting: - Protection against chaff particles, steam, and hot material expelled from the sample port during tryer use - Standard clear safety glasses complying with relevant standards (AS/NZS 1337 in Australia; ANSI Z87.1 in the US)

Face shield: Recommended when pulling samples from the tryer or working near the drum discharge: - Full-face protection against steam jets and hot particle projection - Should be used in addition to, not instead of, safety glasses

Respiratory Protection¶

Roastery airborne hazards include: - VOCs from pyrolysis and Maillard reactions - Fine particulate matter (smoke, chaff fragments) - Carbon monoxide from gas combustion

Primary control: Adequate ventilation is the primary respiratory control; PPE is secondary. If ventilation is functioning correctly and regulatory exposure limits are being met, additional respiratory PPE may not be required for routine roasting tasks.

When respiratory PPE is warranted: - During cleaning and maintenance tasks that disturb accumulated roaster deposits (chaff, oil residue) - When ventilation is temporarily impaired - In high-volume roasting environments where spot-measured VOC or particulate concentrations exceed limits

Appropriate types: - P1/P2 disposable particulate respirators (N95 equivalent): For particulate matter during cleaning tasks - Half-face respirator with OV/P2 cartridges: For combined organic vapour and particulate protection during high-exposure maintenance

Hearing Protection¶

Commercial drum roasters, cooling tray fans, exhaust fans, and afterburner systems produce sustained noise levels that can exceed occupational exposure limits in enclosed roastery spaces:

Assess noise levels at the operator position; if sustained exposure exceeds 85 dB(A), hearing protection is required
Foam earplugs or earmuff-style hearing protection rated at adequate noise reduction
Hearing protection should not prevent the operator from hearing first crack or other critical auditory roast cues; assess whether hearing protectors at appropriate attenuation levels allow adequate auditory monitoring

Key Facts¶

Heat-resistant long-cuffed leather or Kevlar gloves are the most critical PPE item for roaster operators
Closed-toe leather footwear protects against hot bean spillage; synthetic soles and open-toe shoes are unsuitable
Safety glasses minimum for all personnel; face shield recommended during tryer sampling
Ventilation is the primary respiratory control; PPE supplements ventilation but does not replace it
Assess roastery noise levels; hearing protection required if sustained exposure exceeds 85 dB(A)
