Via surface resistivity in ohms per square, measured to the recognised ESD test method. Confirm the exact limit in the HCIS requirement that applies to your site — UNEOM specifies to the value your safety authority mandates.

Are ESD coveralls more expensive?

Yes — 30-40% over standard FR coveralls.

How long does ESD performance last?

Wash-validated to 80 cycles; UNEOM provides per-garment serial tracking.

Is ESD required at every petrochemical site?

In ATEX-zoned areas, yes. UNEOM specifies ESD into the relevant programme tier.

Can ESD and HRC2 be combined?

Yes — UNEOM produces inherent FR cotton coveralls with combined ESD and arc-rated performance; we supply the arc rating in cal/cm² and the test certificate so your safety team can match it to the site hazard assessment.

الحماية من الكهرباء الساكنة في ملابس العمل الصناعية السعودية

In a Saudi petrochemical plant, an electrostatic discharge is not a static-shock annoyance — it is an explosive-environment ignition source. ESD-rated coveralls are the difference between a near-miss and an incident. The HCIS spec is specific; most catalogue products don't meet it.
