Chemical Agents Training in Dublin: Employer Duties in Ireland

Chemical agents training in Ireland is built on a specific piece of legislation: the Safety, Health and Welfare at Work (Chemical Agents) Regulations 2001, as amended. If your Dublin workplace uses cleaning products, solvents, adhesives, fuels, lab reagents or any other hazardous chemical, the Regulations tell you what to assess, what to control, and what employees must be told and trained to do. Our overview of HSA mandatory training requirements in Ireland places this topic alongside others; here we focus on the Regulations themselves.

The law is national, so the same rules apply across Ireland. We read the original 2001 Regulations (S.I. No. 619 of 2001) on the Irish Statute Book, and the amending instruments of 2015 (S.I. No. 623 of 2015), 2021 (S.I. No. 231 of 2021) and 2026 (S.I. No. 127 of 2026). A caution applies throughout: the text we opened for the 2001 Regulations is the version as made, so some cross-references in it were changed by later amendments. Always check the current consolidated text before relying on a particular paragraph.

What the Regulations cover

Regulation 2 defines a chemical agent broadly: any chemical element or compound, on its own or admixed, as it occurs in the natural state or is produced, whether or not it is produced intentionally and whether or not it is placed on the market. Regulation 3 applies the Regulations wherever hazardous chemical agents are or may be present at work, and includes self-employed persons, temporary and fixed-term employees.

The 2015 amendment, according to the Irish Statute Book, revised the definition of "hazardous chemical agent" to align with the EU classification criteria known as CLP.

Risk assessment comes first

Under Regulation 4, the employer must determine whether any hazardous chemical agents are present at the workplace and assess the resulting risk. The assessment must be recorded in writing, and for a new activity, work must not commence until after an assessment of the risk of that activity has been made. The 2015 and 2026 amendments add references to the supplier's safety data sheet under the EU REACH Regulation, and the 2026 amendment says suppliers must provide the relevant safety data sheet plus any additional information needed to complete the assessment.

This ties in with the Safety, Health and Welfare at Work Act 2005. Section 19, as read on the Revised Acts page, requires every employer to identify hazards, assess the risks and be in possession of a written assessment, and to review it after a significant change.

Information, training and consultation (Regulation 9)

Regulation 9 is the central training provision. As originally made, it requires the employer to ensure that employees and/or their safety representatives receive:

• the data used in, and produced by, the risk assessment, updated when a major workplace change alters it;
• information on the hazardous chemical agents at the workplace, including their identity, the risks they pose, relevant occupational exposure limit values and other applicable legislation;
• training and information on the precautions and actions needed to protect themselves and other employees; and
• access to safety data sheets.

Regulation 9(2) provides that the information must be given to the extent and in a form appropriate to the outcome of the risk assessment and kept up to date. Regulation 9 also requires containers and pipes used for hazardous chemical agents to be clearly labelled or identified by their contents and associated hazards, and requires consultation with employees and/or their safety representatives.

The 2015 amendment, according to the Irish Statute Book, changed several cross-references in Regulation 9 (for example, to section 9(3) of the 2005 Act and to the REACH safety data sheet provision). Notice that Regulation 9(2) scales the information to the outcome of the risk assessment. The Regulation does not set a course title, a duration or a certificate.

Prevention, emergencies and employee duties

Training only makes sense alongside the controls it supports. The Regulations also include:

• Prevention and control of exposure (Regulations 5 and 6): measures to prevent or control exposure, including specific protection and prevention measures. We did not read the detail of these provisions in full, so check them if you handle hazardous agents.
• Emergencies (Regulation 8): an action plan for chemical-related emergencies, covering drills, first aid, warning systems, restricted access and protective equipment, plus hazard information for emergency services on request.
• Employee duties (Regulation 7): employees must make full and proper use of the control measures, protective equipment and facilities provided, return equipment after use to the accommodation provided for it, and report any defect to the employer forthwith.

In our view, instruction on how to use and store protective equipment matters because the Regulation 7 employee duty depends on knowing how. Our guide to HSA improvement and prohibition notices looks at how the Authority can act under the 2005 Act; it is no substitute for reading the Regulations themselves.

Health surveillance (Regulation 10)

As originally made, Regulation 10 requires the employer to make provision for appropriate health surveillance where the risk assessment shows a risk, run by an occupational healthcare professional, and to keep an individual health record. Health surveillance is mandatory where a biological limit value for a hazardous chemical agent is listed. The 2026 amendment, according to the Irish Statute Book, says surveillance is mandatory where a biological limit value is listed in a Code of Practice and that employers must tell employees about this requirement before assigning them to tasks with exposure risk.

The 2021 and 2026 amendments

S.I. No. 231 of 2021 was signed on 12 May 2021 and further implemented six EU directives. As read on the Irish Statute Book, it replaced the definition of "occupational exposure limit value" so that limits are set by the Health and Safety Authority in a Code of Practice.

S.I. No. 127 of 2026 was made on 31 March 2026 and, according to the Irish Statute Book, commenced on 9 April 2026. It gives effect to Directive (EU) 2024/869, which changes the limit values for lead and its inorganic compounds and sets a limit value for diisocyanates. It also removes Schedules 1 and 2 of the principal Regulations. The amending Regulations do not state the numerical limits; the Irish Statute Book explanatory note says these work together with changes to the Code of Practice.

A practical approach

These are our suggestions, not legal requirements:

• Build and maintain a register of the chemicals you use, linked to safety data sheets.
• Check your assessment against any lead or diisocyanate use, given the 2026 changes.
• Match training content to the chemicals and tasks in the assessment rather than using generic material.
• Keep a record of who was trained on what, and when, and revisit it when substances or processes change.

Frequently asked questions

Is chemical agents training mandatory?

Regulation 9, as originally made, requires employers to ensure employees and safety representatives receive training and information on the precautions and actions needed to protect themselves and others. It requires information to be given to an extent appropriate to the outcome of the risk assessment, and it does not name a specific course.

Do the Regulations apply to everyday cleaning products?

They apply wherever hazardous chemical agents are or may be present at work. Whether a particular product is hazardous depends on the classification and your risk assessment, so check the safety data sheet.

Who must be given safety data sheets?

As originally made, Regulation 9 requires access to safety data sheets for employees and/or their safety representatives. The 2015 and 2026 amendments update the references to the REACH safety data sheet provision.

Are there new rules on lead and diisocyanates?

S.I. No. 127 of 2026 gives effect to Directive (EU) 2024/869 on lead and diisocyanates and commenced on 9 April 2026. Under the amended definition, occupational exposure limit values are set by the Health and Safety Authority in a Code of Practice, which we have not reproduced here.

Do I need health surveillance?

Where the risk assessment shows a risk, appropriate health surveillance must be made available, and it is mandatory where a biological limit value is listed. Take advice on how this applies to your substances.

Because this area has been amended several times, confirm the current consolidated text and Code of Practice before acting.
