Irritant chemical: definition, examples and how to store them safely
If your company manages irritant chemicals, choosing a specialized operator to store them is key to protecting your people, your inventory and your reputation. Below you will find a practical, decision-oriented guide: what an irritant is, how it is classified, common examples, and what you should require from your logistics partner.
Brief definition: An irritant chemical is a substance or mixture that causes reversible inflammation of skin, eyes or respiratory tract after brief or repeated exposure. In CLP/GHS it is usually identified with the GHS07 (exclamation) pictogram and hazard statements such as H315, H319 or H335.
Why outsource the storage of irritants to a specialized operator
- Reduced operational risk: facilities designed for safe handling, ventilation, containment and signage.
- Regulatory compliance: application of CLP/GHS, procedures and traceability (SDS, batch/expiry records).
- Service continuity: emergency protocols, trained staff and preventive maintenance.
- Controlled costs: fewer incidents, lower shrinkage and faster replenishment thanks to inventory visibility.
- Scalability: capacity for seasonal peaks and projects with requirements by chemical family.
CLP/GHS labelling: pictogram, key H-codes and P-codes
Always check the label and the Safety Data Sheet (SDS). Irritants typically carry:
- Pictogram: GHS07 (exclamation).
- Common hazard statements: H315 (skin irritation), H319 (serious eye irritation), H335 (respiratory irritation).
- Typical precautionary statements: P264, P280, P302+P352, P305+P351+P338, P312.
- Key documentation: SDS (sections 2, 4, 7, 8 and 13) and an up-to-date CLP label.
Differences: irritant vs. corrosive vs. sensitizer
| Class | Typical effect | Reversibility | Pictogram |
|---|---|---|---|
| Irritant | Redness, stinging, cough | Generally reversible | GHS07 (exclamation) |
| Corrosive | Deep chemical damage | Often irreversible | GHS05 (corrosion) |
| Sensitizer | Allergic reaction after exposures | May persist | GHS07 (exclamation) or others as applicable |
Common examples in logistics
Irritation depends on concentration, pH, volatility and exposure time. Typical warehouse examples include:
| Family / example | Irritation risk | Usage notes |
|---|---|---|
| Alcohols (ethanol, isopropanol) | Skin, eye and inhalation | Also flammable; require ventilation and ignition control. |
| Ketones (acetone, MEK) | Skin and eye | Highly volatile; dry out skin and mucosa. |
| Surfactants / detergents | Skin and eye | Irritation linked to concentration. |
| Dilute acids and bases (acetic, citric; dilute NaOH) | Skin and eye | At higher concentrations they can be corrosive. |
| Aromatic solvents (xylene, toluene) | Eye and respiratory | Need effective ventilation and suitable PPE. |
| Mild oxidizers (dilute hypochlorite) | Eye and respiratory | Do not mix with acids or ammonia: risk of irritating gases. |
Safe storage checklist
- Legible CLP labels and SDS accessible at point of use.
- Compatible, closed containers on bunds/drip trays.
- Compatibility segregation (acids/bases/oxidizers/solvents).
- Ventilation and extraction for transfers; ignition source control.
- PPE available and signage for showers/eyewash stations.
- Inventory with lots, expiry dates and rotation (FIFO/FEFO).
- Spill plan with suitable absorbents and approved containers.
What to do in case of exposure to an irritant
- Skin contact: remove contaminated clothing. Wash with soap and water for ≥15 minutes. Check the SDS (Section 4).
- Eye contact: rinse for 15–20 minutes, keep eyelids open. Remove lenses. Seek medical advice if irritation persists.
- Inhalation: move to fresh air; if coughing or dyspnea occurs, seek medical attention.
- Ingestion: do not induce vomiting unless instructed by a physician. Rinse mouth and contact toxicology services.
Note: always follow your internal procedures and the specific instructions in the product’s SDS.
Transport and signage: key points
The health hazard classification for storage (CLP/GHS) does not always match the transport classification (ADR/IMDG/IATA). The same product may be, for example, a flammable liquid (Class 3) and also an irritant. Always check SDS Section 14, UN number, packing group and package/vehicle signage.
Frequently asked questions
– Which pictogram identifies an irritant product?
GHS07 (exclamation), common for skin/eye irritants and STOT SE 3 (respiratory).
– Does an extreme pH imply corrosivity?
Very low or high pH may indicate corrosivity, but classification depends on toxicological data. Check the SDS and label.
– Can I transport an irritant as “non-dangerous”?
Not necessarily. Transport classification may differ from CLP. Review SDS Section 14 and ADR/IMDG/IATA rules.
