What does GHS07 mean?

The exclamation mark pictogram indicates acute toxicity of lower severity (H302/H312/H332), skin and eye irritation (H315/H319), skin sensitisation (H317), and respiratory/narcotic effects (H335/H336). Suppressed when GHS06, GHS05, or GHS08 applies.

Straight answers

What does the exclamation mark pictogram indicate?

The serious-but-not-severe band: acute toxicity category 4, skin and eye irritation, skin sensitisation, and single-exposure organ effects category 3 including narcotic effects. 8 CLP hazard classes lead to it, more than any pictogram except the flame, carrying 9 hazard statements.

Which pictogram is also known as the irritant pictogram?

This one. GHS07 covers skin irritation category 2 and eye irritation category 2A, so it is routinely called the irritant symbol — but irritation is only two of its eight hazard classes. The same picture also means harmful if swallowed, may cause an allergic skin reaction, and may cause drowsiness or dizziness.

What is the black exclamation mark pictogram?

A misunderstanding worth clearing up. The symbol itself is always black — every GHS pictogram is a black symbol on a white background inside a red diamond. There is no separate black-bordered version for CLP labelling; a black-bordered diamond is a transport label, not a hazard pictogram.

When is the exclamation mark removed from a label?

Three of the five precedence rules in Article 26 point at it, and they are the reason a substance can be an irritant with no exclamation mark on the label. GHS06 removes it outright; GHS05 removes it for irritation only; GHS08 removes it for sensitisation when the health hazard is there because of asthma.

How many chemicals carry GHS07?

1,592 substances with a harmonised classification in CLP Annex VI, and it is the most common companion pictogram of all — it appears next to another diamond more often than it appears alone.

Every number here is computed from CLP Annex VI at build time. See all nine pictograms compared.

Which hazard classes require GHS07?

GHS07 is assigned by 8 hazard classes across 11 categories under CLP and UN GHS. The signal word is set by the category, not by the pictogram — which is why the same pictogram can carry both Danger and Warning. The full wording of every code is listed under Associated H-statements below.

Hazard class Ch. Category Signal word H-code
Acute toxicity - oral 3.1 4 Warning H302
Acute toxicity - dermal 3.1 4 Warning H312
Acute toxicity - inhalation 3.1 4 Warning H332
Skin corrosion/irritation 3.2 2 Warning H315
Serious eye damage/eye irritation 3.3 2A Warning H319
Skin sensitisation 3.4 1 Warning H317
Skin sensitisation 3.4 1A Warning H317
Skin sensitisation 3.4 1B Warning H317
Specific target organ toxicity - single exposure 3.8 3 Warning H335
Specific target organ toxicity - single exposure 3.8 3 narcotic Warning H336
Hazardous to the ozone layer 4.2 1 Warning H420

Which pictograms appear next to GHS07

A label rarely carries one diamond. Counted across the 1,592 harmonised substances that carry GHS07 — before the Article 26 precedence rules remove anything.

GHS09 Environmental Hazard 730 · 45.9% GHS08 Health Hazard 478 · 30% GHS05 Corrosion 366 · 23% GHS02 Flame 202 · 12.7% GHS03 Flame Over Circle 16 · 1% GHS01 Exploding Bomb 15 · 0.9% GHS04 Gas Cylinder 5 · 0.3% GHS06 Skull and Crossbones 1 · 0.1%

The exclamation mark is the most common companion pictogram on the site, and its own most frequent partner is the environment — the mild-to-a-person, harsh-to-the-water combination.

When GHS07 is removed from a label

Article 26 of CLP cuts the number of diamonds on a label. 3 of its five rules touch GHS07.

Article 26(1)(b)

If GHS06 applies, GHS07 shall not appear.

The hardest of the three: no exception at all. Only 1 harmonised entry carries both, and on its label the exclamation mark is removed.

Article 26(1)(c)

If GHS05 applies, GHS07 shall not appear for skin or eye irritation — and only for that.

Narrow, and widely over-applied. 366 entries carry both, and most keep the exclamation mark because it comes from something the rule does not cover — acute toxicity category 4, sensitisation, narcotic effects.

Article 26(1)(d)

If GHS08 applies for respiratory sensitisation, GHS07 shall not appear for skin sensitisation or for skin and eye irritation.

Narrower still: it fires only when the health-hazard diamond is there because of asthma. 478 entries carry both pictograms; the rule reaches only the respiratory-sensitiser slice of them.

Nothing in Article 26 makes GHS07 optional in the other direction unless a rule above says so. All five precedence rules, with the number of substances each one affects.

Storage & handling requirements

Provide adequate ventilation in work areas. Wear appropriate PPE: gloves, eye protection, and respiratory protection if vapour concentrations may exceed OELs. Keep containers closed when not in use. Wash hands thoroughly after handling.

Regulatory context (CLP / OSHA / REACH)

CLP Acute Toxicity Cat. 4 and various irritation/sensitisation categories. Suppressed on label by GHS06 (acute tox. Cat. 1–3) and GHS05 per CLP Article 26. OSHA HCS 2012 aligns with these classifications.

Transport marking: GHS vs ADR/DOT

Harmful substances (Class 6.1 PG III) may display GHS07 for transport. However, many GHS07-classified substances fall below ADR transport thresholds and do not require hazmat placards for road transport.

Printing GHS07 on a label

A square set at a point — a diamond — with the black symbol on a white background and a red frame wide enough to be clearly visible. An all-black frame is a transport label, not a CLP pictogram. Size is set twice over: each pictogram must cover at least one fifteenth of the minimum label area required by Article 17, and must never be smaller than 1 cm². On a package of 3 litres or less that works out to 10 × 10 mm as the floor, and 16 × 16 mm where it fits.

Source: Regulation (EC) No 1272/2008, Annex I, 1.2.1.1–1.2.1.4 and Table 1.3 — the full table for all four package sizes. Building an actual label? The label constructor lays it out at the right proportions.
