Thermal degradation fumes
Heated polymer releases irritant vapours at the barrel and die head, particularly during purge and colour-change operations.
Plastic sector
Occupational health for plastics and polymer processing
Injection moulding, extrusion and granulation put workers next to heated polymer and continuous machine noise for a full shift. The health signal shows up first in lung function and hearing thresholds, both of which trend slowly enough to miss without year-on-year comparison.

Exposure profile
What your people areactually exposed to
The hazards below drive every test in the plastic protocol. Nothing is included because it is standard — each one answers a specific exposure.
Continuous machine noise
Granulators and crushers commonly exceed 90 dB(A), producing early high-frequency hearing loss that workers rarely notice themselves.
Contact burns and skin exposure
Hot surfaces, mould faces and additive handling drive dermatological screening for the moulding and tool-change crew.
Repetitive handling
De-gating, trimming and packing cycles create wrist and shoulder loading that warrants ergonomic assessment.
Examination protocol
The test panel, andthe reason for each test
This is the panel an inspector will ask you to justify. Every row states the exposure it answers and the cycle it runs on.
| Test | Why it is in the panel | Frequency |
|---|---|---|
| Audiometry | Granulator and crusher noise | Annual |
| Spirometry (PFT) | Thermal degradation fumes | Annual |
| Dermatological assessment | Additive and burn exposure | Annual |
| Vision screening | Fine inspection work | Annual |
| Musculoskeletal evaluation | Repetitive cycle loading | Annual |
Statutory basis
What the law expectsof this sector
We prepare the registers and evidence in these formats as part of the programme — not as an add-on when an inspection is announced.
Factories Act 1948, Section 89 — notice of occupational disease including noise-induced hearing loss
State Factory Rules — hearing conservation programme where exposure exceeds 85 dB(A)
Section 41-C obligations where hazardous additives are in use
ISO 45001 clause 6.1.2 — hazard identification supported by health surveillance evidence
