Question 1

What is CLASS 2013?

Accepted Answer

CLASS 2013 refers to Malaysia's Occupational Safety and Health (Classification, Labelling and Safety Data Sheet of Hazardous Chemicals) Regulations 2013. It requires all hazardous chemicals to be properly classified, labeled, and accompanied by Safety Data Sheets. The regulations came into force on April 1, 2015, and are enforced by DOSH (Department of Occupational Safety and Health).

Question 2

Who needs a Safety Data Sheet (SDS) in Malaysia?

Accepted Answer

All manufacturers, importers, and suppliers of hazardous chemicals in Malaysia must prepare and provide SDS compliant with CLASS 2013. Employers must also ensure SDS are available to workers who handle hazardous chemicals. This includes chemicals used in manufacturing, laboratories, construction, and any workplace setting.

Question 3

How long does SDS preparation take?

Accepted Answer

Typical turnaround is 3-7 business days for standard products. Simple products with complete data may take 3-5 days, while complex formulations or products requiring extensive research may take 7-14 days. Rush service may be available for urgent requests.

Question 4

Do you handle confidential formulations?

Accepted Answer

Absolutely. We maintain strict confidentiality protocols and can work with proprietary formulations under NDA. We can use concentration ranges and generic chemical identities where permitted by regulations to protect your trade secrets while maintaining compliance.

Question 5

What is GHS and how does it relate to CLASS 2013?

Accepted Answer

GHS stands for Globally Harmonized System of Classification and Labelling of Chemicals, developed by the United Nations to standardize chemical hazard communication worldwide. Malaysia's CLASS 2013 is based on GHS principles and adopts GHS classification criteria, pictograms, and SDS format. This alignment helps Malaysian companies comply with international standards.

Question 6

What are the penalties for non-compliance with CLASS 2013?

Accepted Answer

Penalties for non-compliance include fines up to RM 50,000, imprisonment up to 2 years, or both for serious violations. DOSH can also issue workplace shutdown orders for imminent dangers. Repeat offenders face higher penalties. Proper compliance is essential to avoid legal liability and protect worker safety.

Question 7

Do I need SDS in both English and Malay?

Accepted Answer

CLASS 2013 allows SDS in either English or Malay. However, providing bilingual SDS is strongly recommended to ensure all workers can understand the safety information, especially in workplaces with Malay-speaking workers. Bilingual SDS improve safety communication, demonstrate commitment to worker safety, and reduce liability from miscommunication.

Question 8

How often should SDS be updated?

Accepted Answer

SDS should be updated whenever: new hazard information becomes available, formulation changes occur, regulatory requirements change, or new uses are identified. As best practice, review and update SDS every 3-5 years even without changes. CLASS 2013 requires SDS to be current and accurate at all times.

Question 9

What information do you need to prepare an SDS?

Accepted Answer

We typically need: product name and intended use, complete formulation (ingredients and concentrations), physical and chemical properties (if available), existing test data (toxicity, ecotoxicity, etc.), intended market and applications, and any existing SDS or classification for review services. We can work with incomplete data and help identify what additional testing may be needed.

Question 10

What are hazard pictograms and how many are there?

Accepted Answer

Hazard pictograms are standardized GHS symbols that visually communicate the type of hazard. There are 9 pictograms covering different hazard types: flame (flammable), flame over circle (oxidizer), exploding bomb (explosive), gas cylinder (compressed gas), corrosion (corrosive), skull and crossbones (acute toxicity), exclamation mark (health hazard/irritant), health hazard (serious health effects), and environment (aquatic toxicity).

Question 11

What is the difference between "Danger" and "Warning" signal words?

Accepted Answer

"Danger" is used for more severe hazards (Categories 1 and 2), while "Warning" is used for less severe hazards (Categories 3 and above). The signal word is determined by the most severe hazard classification of the chemical. Only one signal word appears on a label, even if multiple hazards are present.

Question 12

How do I prepare for a DOSH inspection?

Accepted Answer

Prepare by: ensuring all SDS are current and accessible to workers, verifying all chemical labels are compliant with CLASS 2013, maintaining complete classification records, keeping chemical inventory up to date, training workers on chemical hazards and SDS location, organizing documentation for easy access, and conducting a pre-inspection gap assessment. We offer compliance gap assessment services to help you prepare.

Question 13

What records must I keep for chemical compliance?

Accepted Answer

You must maintain: classification records for all hazardous chemicals, SDS for at least 30 years, records of worker training on chemical hazards, chemical inventory, incident reports related to chemical exposure, and any correspondence with DOSH. All records must be available for DOSH inspection upon request.

Question 14

How are chemical mixtures classified?

Accepted Answer

Mixtures are classified using three methods in order of preference: (1) test data on the mixture itself, (2) bridging principles if similar tested mixtures exist, or (3) cut-off values and calculation methods based on ingredient hazards and concentrations. The classification considers physical, health, and environmental hazards according to GHS criteria.

Question 15

Do I need to register my chemicals with DOSH?

Accepted Answer

CLASS 2013 does not require general chemical registration with DOSH. However, you must maintain proper classification records, SDS, and labels. Some specific chemicals (like pesticides) may have additional registration requirements under other regulations. The focus is on proper hazard communication rather than registration.

Question 16

What if I am importing chemicals with foreign SDS?

Accepted Answer

Foreign SDS must be reviewed and adapted to meet Malaysian CLASS 2013 requirements. This includes ensuring proper classification according to Malaysian standards, adding local supplier information (name, address, phone), verifying compliance with all 16 required sections, and translating to Malay if needed. We offer SDS review and adaptation services for imported chemicals.

Question 17

What industries do you serve?

Accepted Answer

We serve a wide range of industries including: chemical manufacturing, pharmaceuticals, cosmetics and personal care, industrial chemicals, agrochemicals, paints and coatings, adhesives and sealants, cleaning products, automotive, electronics, oil and gas, and laboratories. Any business handling hazardous chemicals in Malaysia can benefit from our services.

Question 18

Do you offer training on CLASS 2013 and chemical safety?

Accepted Answer

Yes, we offer comprehensive training on CLASS 2013 requirements, GHS classification and labeling, SDS preparation and interpretation, chemical safety in the workplace, and DOSH inspection preparation. Training can be customized for your specific industry and workforce needs. Contact us to discuss your training requirements.

Question 19

What is included in a compliance gap assessment?

Accepted Answer

Our compliance gap assessment includes: review of existing SDS documents for completeness and accuracy, verification of chemical classifications, label compliance assessment, documentation and record-keeping review, workplace chemical inventory assessment, gap identification and prioritization, remediation recommendations, and implementation roadmap development. We provide a comprehensive report with actionable recommendations.

Question 20

Can you help with international chemical compliance?

Accepted Answer

Yes, we can help with GHS-based compliance for other countries and regions. While CLASS 2013 is Malaysia-specific, GHS is internationally recognized. We can prepare SDS according to GHS format and provide guidance on country-specific requirements for markets like Singapore, Thailand, Indonesia, EU, USA, and others.
