Chemical law
Three layers of compliance: national law, corporate standards and best practice
On large projects, chemical management answers to three sets of rules at once. Where they overlap, the strictest one applies.
For chemical management on oil and gas and other large projects, compliance has three layers.
| Layer | Examples | What it sets |
|---|---|---|
| National law | National Environment Act Cap. 181; OSH Act Cap. 231; Hazardous Chemicals Regulations, 2024; Waste Management Regulations, 2020; Oil Spill Regulations, 2020; ESIA certificate conditions | The legal minimum: licences, registration, labelling, reporting and penalties |
| Corporate standards | Operator and contractor HSE management systems, chemical approval procedures, PPE matrices, incident reporting systems | Company-wide rules, often stricter than national law |
| International conventions and best practice | GHS; Basel, Rotterdam, Stockholm and Minamata Conventions; Montreal Protocol; ILO Chemicals Convention (No. 170); ISO 45001 and ISO 14001; IFC Performance Standards | Methods, benchmarks and expectations from lenders and international partners |
How the layers interact
- National law is the floor. No corporate procedure can lower a legal requirement. A company rule that allows decanting into unlabelled bottles does not override the Regulations.
- Corporate standards often go further. Many operators require formal approval before any new chemical comes on site, with an SDS review, risk assessment and authorisation. They may also require substitution of carcinogens where possible, or 16-section SDSs in English at every point of use.
- Best practice fills gaps. Where the law is silent, international practice usually decides. Examples include bund sizing, quarterly SDS library reviews and a 2–6 week follow-up after training.
The working rule. Where two layers set different requirements, apply the more protective one, and record which source you followed.
Common best practices
- Keep an up-to-date, GHS-compliant inventory and SDS library, reviewed quarterly.
- Size secondary containment to at least 110% of the largest container.
- Store incompatible chemicals in separate, labelled cabinets.
- Run induction and annual refresher training with practical drills.
- Carry out routine inspections and audits, and track corrective actions to closure.
What to do
- Build one compliance matrix for your site, listing each obligation, its source layer and its owner.
- Flag every place where a corporate standard is stricter than the law, so auditors understand why.
- Review the matrix whenever a regulation, ESIA condition or company standard changes.
How INRC can help
We build site compliance matrices that bring national law, ESIA certificate conditions, company standards and lender requirements into one place, and we audit against them. See our environmental audits and management systems services. Contact us to discuss your site.
