The practical answer
Under OSHA's laboratory standard, keep incoming labels intact, keep the supplier's SDS readily accessible, cover the new chemical in your chemical hygiene plan and train staff before they work with it. A secondary container needs at least the product identifier and general hazard information, unless it is only for the immediate use of the person who filled it. Employers must update workplace labels and training under the 2024 HazCom revision by 20 November 2026.
Evidence, method & source dates ↓Which OSHA rule applies to your lab
29 CFR 1910.1450, the laboratory standard, applies to employers engaged in the laboratory use of hazardous chemicals. Laboratory use has four conditions: manipulations are on a laboratory scale, meaning containers one person can easily and safely handle; multiple procedures or chemicals are used; the work is not part of or a simulation of a production process; and protective practices and equipment are available and in common use. [1]
Where a lab meets that definition, the Hazard Communication Standard (1910.1200) still applies in part. Section (b)(3) requires labs to keep incoming labels intact, keep SDSs received with shipments readily accessible during each work shift, and provide information and training, except for the notice of where the written hazard communication program is kept. [2] OSHA's laboratory standards page also lists PPE, respiratory and other general industry rules that can apply in labs, and notes that State Plans may be stricter. [3]
This checklist covers the paperwork and labeling that arrive with a new chemical. It contains no handling procedures for any use of the material and no exposure assessment, which belong to your chemical hygiene officer.
Update the chemical hygiene plan
1910.1450(e) requires a written chemical hygiene plan capable of protecting employees, reviewed at least annually. [1] A new peptide rarely needs a new plan, but it should be checked against each required element so the annual review has something to verify.
| CHP element (1910.1450(e)(3)) | Question for a new peptide |
|---|---|
| Standard operating procedures | Does an existing SOP cover weighing and solution work for this material, or is a new one needed? [1] |
| Control measure criteria | Which engineering controls and PPE does the SDS indicate? [1] |
| Fume hoods and protective equipment working | Is the equipment the SOP relies on inspected and functioning? [1] |
| Information and training | Who needs training before first use? [1] |
| Prior approval | Does your plan require approval before work with this class of chemical? [1] |
| Medical consultation | Is the contact route documented if an exposure occurs? [1] |
| Designated personnel | Is the chemical hygiene officer aware of the addition? [1] |
| Particularly hazardous substances | Does the SDS classification trigger designated areas or extra containment? [1] |
Incoming containers, SDS and small vials
Both standards say labels on incoming containers of hazardous chemicals must not be removed or defaced, and SDSs received with incoming shipments must be kept and readily accessible to laboratory employees. [1] [2]
Peptides often arrive in very small vials, and the 2024 HazCom revision added small-container rules for manufacturers, importers and distributors. Where a full fold-back or pull-out label is not feasible, a container of 100 ml or less must show at least the product identifier, pictograms, signal word, the manufacturer's name and phone number, and a statement that full label information is on the immediate outer package. For a container of 3 ml or less, if the manufacturer, importer or distributor can show that any label would interfere with normal use, no label is required, but the container must still bear at least the product identifier. [2]
For both cases the immediate outer package must carry the full label and a statement that the small containers must be stored in that outer package when not in use. [2] For receiving staff, that makes the outer box part of the label: record that it was received, keep it, and store the vials in it.
Secondary container labels
When a chemical is transferred to another container, 1910.1200(f)(6) lets the employer either copy the shipped label information or use a workplace label with the product identifier and words, pictures, symbols or a combination that give at least general information about the hazards. [2] A portable container does not need a label if it is intended only for the immediate use of the employee who performed the transfer. [2]
Institutions often set tighter rules. The University of Washington's EHS page, for example, asks for the identity of the contents spelled out without abbreviations, the signal word and hazards if known, and recommends the preparer's name and date for working solutions. Its exception applies only when the container stays under the direct control of the person who prepared it and will be emptied during that shift. [4] Check your own institution's rule before using the template below.
| Label field | Required or recommended | Example for a transferred aliquot |
|---|---|---|
| Product identifier | Required by (f)(6) [2] | Full peptide name as on the SDS, not a lab nickname |
| Hazard information | Required: at least general hazard information [2] | Signal word and pictogram copied from the supplier label, or "No GHS hazard classification on SDS dated ..." if that is what the SDS says |
| Supplier lot number | Recommended for traceability | Lot from the certificate of analysis |
| Concentration and solvent | Optional per UW [4] | Only if the container holds a solution |
| Prepared by and date | Recommended per UW [4] | Initials and ISO date |
| Inventory or container ID | Recommended | Links the aliquot to the parent container entry |
Training records and the November 2026 date
1910.1450(f) requires information and training at an employee's initial assignment to a work area where hazardous chemicals are present and before new exposure situations, with refresher frequency set by the employer. Training covers how to detect releases, the physical and health hazards of chemicals in the work area, protective measures and the applicable details of the chemical hygiene plan. [1]
The 2024 HazCom revision took effect on 19 July 2024. For substances, manufacturers, importers and distributors had to comply by 19 May 2026, and employers must update workplace labeling and training by 20 November 2026. Mixtures follow a later schedule ending on 19 May 2028 for employers. [2] A lab adding a new peptide this autumn should make sure its secondary labels and training reflect the current supplier labels.
One-page checklist
Use this as the record for each new chemical. Keep it with the inventory entry and the SDS.
- SDS received, saved where lab staff can reach it during every shift, and dated. [1] [2]
- Incoming labels and the outer package for small vials kept intact. [2]
- Inventory entry created with name, CAS number if any, lot, quantity, location and owner.
- Chemical hygiene plan checked against each element; changes noted for the annual review. [1]
- Secondary label template agreed with your EHS office. [2] [4]
- Training recorded for each person before first work with the chemical. [1]
- Exposure measurement or medical consultation records, if any arise, kept under 1910.1450(j). [1]
Questions before you decide
Do I need to label a tube I fill and use immediately?
Under 1910.1200(f)(8), no label is required if the portable container is only for the immediate use of the employee who transferred the chemical.
What must a secondary container label say at minimum?
1910.1200(f)(6) allows the product identifier plus words, pictures or symbols giving at least general information about the chemical's hazards.
Why does my peptide vial carry only a name?
Under the 2024 small-container rule, a container of 3 ml or less must bear at least the product identifier when any label would interfere with normal use; the outer package must carry the full label.
When must training be given?
1910.1450(f) requires it at initial assignment to a work area where hazardous chemicals are present and before new exposure situations.
