H₂S corrodes metal.
Methane accumulates.
The P-trap is a vector.

Industrial plants and warehouses have large floor drains and central trenches. Hydrogen sulphide from the biofilm corrodes reinforcement bars, services and electronics. Methane and other gases accumulate in poorly ventilated spaces — an explosive hazard. Green Drain™ is a safety measure, not a luxury.

Problem & solution

Industrial P-traps are the worst maintained.

In a big plant everyone minds their own patch — nobody looks at the floor drains. Biofilm grows, H₂S corrodes metal, and gases accumulate.

Without Green Drain™

  • H₂S corrodes rebar, sewer pipes, and ventilation ducts.
  • Methane (CH₄) generated in drain biofilm — it builds up in poorly ventilated spaces
  • Cold stores: the trap freezes and cracks — the water is lost and the smell follows.
  • Distribution Centres (FMCG): Flies and pests in biofilm — a HACCP risk for food logistics
  • Statutory inspection requires hazard controls for workers

With Green Drain™

  • The temperature range covers cold storage and hot process zones.
  • Resistant to 5 % NaOH, 3 % HNO₃, peracetic acid, quaternary amines
  • No water, so nothing to freeze in the cold store
  • H₂S and methane remain in the sewer system — worker safety
  • ATEX-aware design — the seal is not a source of sparks.
Industrial regulatory framework

Safety is a legal requirement.

EU Directive 2014/34 (ATEX) regulates the protection of equipment for explosive atmospheres. Workplace hazard controls in industry are subject to statutory inspection. For food logistics, BRC and IFS audits require environmental monitoring as standard.

Regulatory framework: EUR-Lex for EU directives — EU 2017/745 (MDR), EU 178/2002 (food safety), EU 1935/2004 and EU 10/2011 (food contact materials), EU 528/2012 (BPR), EU 2014/34 (ATEX). Standards: EN 1253-1 (floor P-traps, water seal ≥50 mm), EN 1253 Parts 6/7/8 (gullies with a water seal below 50 mm, with mechanical closure, and combined types; 2023 editions), HACCP International RG-04, ASSE 1072-2020, NSF/ANSI 2, HSE SARI guidelines.

Implementation

The whole plant, in maintenance cycles.

Industrial sites have scheduled shutdowns. Our technicians go in during that window, fit the seals and are out again.

01

Audit

Plant mapping — process, cold storage, shipping, sanitation.

02

Specification

The QHSE department takes the documentation for environmental compliance.

03

Pilot

One line or chamber — 30 days, H₂S measurement at strategic points.

04

Roll-out

During the planned shutdown — the entire plant in 1–3 days.

Model Recommendation

Recommended sizes by zone type.

Irish industrial sites range from pharma manufacturing in Cork and Limerick, FMCG and food-logistics distribution centres around Dublin / Naas / Ballymun, cold-storage and 3PL hubs along the M50 corridor, to data centre support facilities and chemical warehousing under IDA Ireland and HSA oversight. A typical Irish site runs 4–6 different drain sizes across production, sanitary and utility zones.

Green Drain™ Recommended for your industry.

  • Cold stores and blast freezersGD 3 or GD 4Resistance to thermal shock.
  • Central channels between lines (gully channels)GD 5 or GD 6.
  • Chemical storage facilities, ATEX zones, staff sanitationGD 3 or GD 4.
