What is a Chemical Register and How to Write One
A chemical register is an essential tool in workplace safety, particularly in industries that involve the use of hazardous substances. It is a comprehensive document that lists all chemicals present at a workplace, along with relevant details such as their properties, associated risks, control measures, and compliance with legal standards.
The purpose of a chemical register is to ensure that all chemicals are managed safely and that employees are adequately informed about the substances they are exposed to, in compliance with the USECHH Regulations 2000. In this article, we will explore the importance of a chemical register and provide guidance on how to create one by breaking down the process into sections A, B, and C of the typical chemical register form.
Chemical register must be prepared as per Guidelines for the Preparation of a Chemical Register by the Department of Occupational Safety and Health, DOSH.
Understanding the Importance of a Chemical Register
A chemical register serves as a critical component of workplace safety management. It helps in the identification and control of hazardous chemicals, thereby minimizing the risk of exposure to employees.
By maintaining a detailed chemical register, companies can ensure compliance with occupational health and safety regulations. Moreover, a chemical register provides a centralized source of information that can be quickly accessed during inspections or in the event of an emergency.

Why is it Important?
Employee Awareness – It ensures that all employees are informed about the chemicals they might come into contact with, including the associated risks and safety measures.
Compliance with Regulations – A chemical register is often a legal requirement. Regulatory bodies may demand it as proof that a company is managing its hazardous substances responsibly.
Risk Management – By listing all chemicals and their associated hazards, a chemical register helps in identifying and managing risks. This is crucial in preventing workplace accidents and illnesses.
Emergency Preparedness – In the event of a chemical spill or exposure, the chemical register provides vital information on how to handle the situation, including the necessary safety precautions and first-aid measures.
How to Write a Chemical Register
Creating a chemical register is a systematic process that involves several key steps. To make the process more manageable, the chemical register is typically divided into sections. Each section captures specific information necessary for the safe management of chemicals in the workplace.
Below, we’ll break down the process into sections A, B, and C, based on the structure of a typical chemical register form.
Fill Up Section A – Company Information
The first section of the chemical register is dedicated to collecting detailed information about the company. This section is crucial as it provides context and ensures that the register is specific to the workplace where it will be used.
To effectively document Section A, gather all necessary company information in advance. Ensure accuracy, as this section forms the foundation of the chemical register and will be referenced in subsequent sections.

1. Company Name and Address
Start by documenting the full legal name of the company and its physical address. This ensures that the register is correctly associated with the specific workplace.
2. Contact Details
Include the company’s telephone number and email address. These contact details are essential for any follow-up actions, whether by regulatory bodies or internal audits.
3. Company Activity
Provide a brief description of the company’s activities, focusing on operations that involve the use of hazardous chemicals. This information helps to contextualize the types of chemicals that might be present in the workplace.
4. DOSH Registration Number
If applicable, include the Department of Occupational Safety and Health (DOSH) registration number, which may be required for compliance and inspection purposes.
5. Code of Sector and Class of Industry
Specify the industry sector and class, referencing standardized codes that categorize the company’s operations.
Fill Up Section B – List of Chemicals Hazardous to Health
Section B is the core of the chemical register, where each hazardous chemical used or stored in the workplace is documented. This section is critical for risk management and compliance with safety regulations.
To fill out Section B, conduct a thorough inventory of all hazardous chemicals in the workplace. Utilize Safety Data Sheets (SDS) to obtain accurate information on each chemical. Ensure that all details are meticulously recorded, as this section is essential for assessing workplace risks and implementing control measures.

1. Location
Document the specific location within the workplace where each chemical is used or stored. This might include details such as the building, floor, or room number.
2. Chemical Name and Product Name
List the common name (product name) and the scientific name (chemical name) of each substance.
3. CAS Number
Include the Chemical Abstracts Service (CAS) number, which is a unique identifier for each chemical.
4. Physical Form of Chemical
Specify whether the chemical is in a solid, liquid, or gaseous state.
5. Quantity
Record the amount of each chemical present in the workplace. This can be documented in terms of volume, mass, or other relevant units.
6. Number of Workers Exposed
Indicate the number of employees who are potentially exposed to each chemical during their work processes.
Fill Up Section C – Name of Person Who Prepared or Reviewed the Register
Section C identifies the individuals responsible for preparing and reviewing the chemical register. This section is important for accountability and ensures that the register is regularly updated and maintained.
Ensure that Section C is completed by the relevant personnel, typically safety officers or managers responsible for chemical safety in the workplace. Regularly review and update this section to reflect any changes in personnel or workplace practices.
- Names and Titles – Document the full names and job titles of the individuals who prepared and reviewed the register.
- Dates – Include the dates when the register was prepared and when it was last reviewed. Regular reviews are essential to keep the register up-to-date with any changes in the workplace.
- Signatures – Obtain signatures from the individuals responsible for preparing and reviewing the register. This formalizes the process and adds a layer of verification to the document.
A chemical register is not merely a compliance requirement; it is a fundamental component of ensuring workplace safety. By meticulously documenting company information, listing hazardous chemicals, and designating responsible personnel, you take proactive steps in managing risks and safeguarding your employees.
