Chemical labels: 6 items to check before dispatch

The six items form an editorial checklist for dispatchers and team leads verifying containers before departure. The first item is the product identifier, defined as the name or number used for a hazardous chemical on a label or in the SDS, according to Legal Information Institute. The remaining five items—signal word, hazard statement, pictogram, precautionary statement, and supplier name with address and telephone—are part of the same label structure described in the cited source.

For coil cleaner or solvent on the truck, use the six items as an editorial checklist, subject to applicable labeling requirements and exceptions. The product identifier links the physical container to the Safety Data Sheet. The signal word indicates the severity of the hazard. A hazard statement is a specified label element for each hazard class and category. The pictogram provides a visual cue for the hazard class. A precautionary statement is a specified label element for each hazard class and category. The supplier name, address, and telephone number allow for rapid contact in an emergency.

Do not mix the US label list with Canadian or New Zealand update rules. Each jurisdiction has distinct requirements for label maintenance and content. The US definitions apply to the specific federal standard cited. Check US, Canadian and New Zealand labeling requirements separately. Keep the checklist focused on the six items named in the quoted US definitions.

Check these six items on the container before the truck leaves.

• Product identifier: Confirm the chemical name or code is visible.
• Signal word: Look for “danger” or “warning” to gauge severity.
• Hazard statement: Read the line describing the specific hazard class.
• Pictogram: Verify the specified symbol for the hazard category.
• Precautionary statement: Note the required safety measures listed.
• Supplier details: Find the name, U.S. address, and U.S. telephone number.

The label elements include the specified pictogram, hazard statement, signal word, and precautionary statement for each hazard class and category, according to Legal Information Institute. The signal words used are “danger” and “warning,” with “danger” for more severe hazards and “warning” for less severe ones, according to Legal Information Institute.

The federal text defines the required label elements as the specified pictogram, hazard statement, signal word, and precautionary statement for each hazard class and category, according to Legal Information Institute. These four components form the core hazard communication block on the container. Before loading a bottle of coil cleaner, check its label against the applicable requirements, accounting for small-container and immediate-use exceptions.

Signal word The signal words used in this section are “danger” and “warning,” according to Legal Information Institute. The text specifies that “danger” is used for the more severe hazards, while “warning” is used for the less severe, according to Legal Information Institute. You must identify which of these two words appears on the label to gauge the severity level indicated by the manufacturer. The signal words distinguish more severe hazards from less severe hazards.

Pictogram Eight pictograms are designated under this standard for application to a hazard category, according to Legal Information Institute. The pictogram is one of the label elements defined for each hazard class and category, according to Legal Information Institute. You should verify that the correct symbol is printed on the container. The standard designates eight specific pictograms, but the label must display the one applicable to the specific hazard class and category of the chemical in question.

Hazard statement The hazard statement is listed as a required label element for each hazard class and category, according to Legal Information Institute. Hazard statements belong to the specified label elements for each hazard class and category. It is part of the specified label elements that must be present. You need to read this line to understand the specific risks associated with the product. The statement is tied to the hazard class and category defined for that chemical.

Precautionary statement The precautionary statement is also a required label element for each hazard class and category, according to Legal Information Institute. Precautionary statements belong to the specified label elements for each hazard class and category. It is one of the four core elements defined in the standard. You should check that this statement is visible and readable on the container before it is loaded.

Supplier contact details The label must include the name, U.S. address, and U.S. telephone number of the chemical manufacturer, importer, or other responsible party, according to Legal Information Institute. This contact information is a distinct requirement from the hazard elements. You must verify that the name, address, and telephone number are all present. This information allows you to contact the source if you have questions about the chemical or need further information.

US small-container labeling provisions address containers with a capacity of 100 ml or less, according to Legal Information Institute. This specific threshold applies to the 29 CFR § 1910.1200 - Hazard communication. | Electronic Code of Federal Regulations (e-CFR) | US Law | LII / Legal Information Institute page. The rule sets a distinct requirement for smaller volumes compared to standard industrial drums. When checking a small bottle of coil cleaner or solvent on the truck, verify that the label meets this minimum standard for containers under this size limit.

A separate provision addresses portable containers used within the workplace. The employer is not required to label portable containers into which hazardous chemicals are transferred from labeled containers, and which are intended only for the immediate use of the employee who performs the transfer, according to Legal Information Institute. This exemption applies specifically to the 29 CFR § 1910.1200 - Hazard communication. | Electronic Code of Federal Regulations (e-CFR) | US Law | LII / Legal Information Institute context. It covers situations where a technician pours a chemical from a main labeled container into a smaller, portable vessel for immediate application. The key condition is that the container is intended only for the immediate use of the employee who performs the transfer. If the container is stored for later use, or used by another employee, this exemption does not apply.

The table below separates each publisher’s specific rule from the others. Each row names the publisher and cites the definition or requirement found on their page. Do not mix the US label elements with the Canadian update timing or the New Zealand and UK statements.

This US definition groups four specific components together for each hazard.

CCOHS states that labels are required to be updated within 180 days of the supplier being aware of the new information, according to CCOHS. This Canadian rule sets a specific timeframe for updates after new information becomes known.

WorkSafe New Zealand notes that it is never safe to have hazardous substances in unlabelled, or incorrectly labelled, containers, according to WorkSafe New Zealand. This New Zealand statement addresses the safety of container labeling in general.

The Health and Safety Executive explains that hazard pictograms alert us to the presence of a hazardous chemical, according to Health and Safety Executive. This UK statement describes the function of the pictogram symbol.

Keep these rules separate when checking a truck. The US page defines the elements, the Canadian page sets the update window, the New Zealand page warns against unlabelled containers, and the UK page describes the pictogram’s purpose. Do not apply the 180-day update rule to the US label elements or the UK pictogram definition.

Check the container against the rules governing its use. For labeling governed by Canadian requirements, check the 180-day update timing. For labeling governed by US requirements, check the applicable label elements and exceptions. If the container is unlabelled, the New Zealand statement applies to the safety of the substance.

The six-item checklist described earlier applies to the US label structure. Rules in other jurisdictions operate differently and must not be mixed into that list.

In Canada, the CCOHS page titled "CCOHS: WHMIS - Labels" specifies that labels are required to be updated within 180 days of the supplier being aware of the new information, according to CCOHS. Keep this Canadian 180-day update window separate from the US checklist. The same CCOHS page notes that a label for a mixture containing ingredients with unknown toxicity in amounts higher than or equal to 1% must include a statement indicating the percent of the ingredient or ingredients with unknown toxicity, according to CCOHS. For containers holding 100 mL or less, the CCOHS page states they are exempt only from the requirement to have precautionary or hazard statements on the label, according to CCOHS. This exemption is specific to the Canadian context described on that page and should not be assumed for US small containers.

In New Zealand, WorkSafe New Zealand’s page titled "Labelling | WorkSafe" states that if you are supplied with hazardous substances you must make sure that the label is maintained; that it stays on the container and can be read, according to WorkSafe New Zealand. The same page adds that if you decant or transfer substances from a large container into smaller ones (eg for ease of use), the containers must be labelled, according to WorkSafe New Zealand. These are maintenance and decanting rules for New Zealand and are distinct from the US label item definitions.

Keep these three Canadian rules and two New Zealand rules separate from the six US label items. Before departure, check chemical labels against the requirements of the jurisdiction governing their use.

Record the six checklist items you can read on the container of one chemical on the truck. The product identifier is the name or number used for a hazardous chemical on a label or in the SDS, according to Legal Information Institute. Fill in the value you see on the container for each item.

Pick one chemical already on the truck and mark which of the six label items you can read on its container.

• Field Service Work Order Checklist for Dispatch Handoffs
• Customer arrival updates: 4 messages and owners
• Move a booked visit: 3 rules and 6 fields

Which words does the US page use for the two signal words?

The US page identifies “danger” and “warning” as the signal words used in this section. According to Legal Information Institute, “danger” is used for the more severe hazards, while “warning” is used for the less severe.

What is a product identifier?

A product identifier is the name or number used for a hazardous chemical on a label or in the SDS. This definition appears in the federal text cited by Legal Information Institute.

What does the Canadian page say about a label that is 180 days out of date?

The Canadian source states that labels are required to be updated within 180 days of the supplier being aware of the new information. This timing rule is specific to the Canadian context described by CCOHS.

When can a small workplace container skip a full label?

The US page notes that an employer is not required to label portable containers into which hazardous chemicals are transferred from labeled containers, if they are intended only for the immediate use of the employee who performs the transfer. This immediate-use exception is detailed by Legal Information Institute.

Does a pictogram replace the supplier name and phone number?

No, the supplier name, address, and telephone number are distinct required elements. The US page lists the name, U.S. address, and U.S. telephone number of the chemical manufacturer, importer, or other responsible party as a separate requirement, according to Legal Information Institute.
