Introduction 

The Occupational Safety and Health Administration’s (OSHA) Hazard Communication Standard (HazCom), 29 CFR 1910.1200, sets thorough mandates for employers on management, availability, and presentation of Safety Data Sheets (SDSs). These requirements form the basis of protecting workers who work with hazardous chemicals in the workplace. Familiarity and adherence to these requirements are critical to ensuring workplace safety and preventing regulatory offenses. 

Understanding Employers’ Obligations Under OSHA’s Hazard Communication (HazCom) Standard 

1. Core SDS Availability Requirements

Under the HazCom standard, employers have, non-negotiable responsibilities for SDS availability beyond merely acquiring these documents. Under the regulation, employers must keep on hand copies of SDSs for every hazardous chemical in their workplace and make these documents immediately available to employees during every work shift when they are in their workstations. This requirement for access is absolute – workers need to have instant access to SDS data without impediment, such as seeking approval from supervisors. 

The term “readily accessible” has been defined by OSHA interpretations to imply direct access to SDSs. Workers should never be forced to ask a supervisor for an SDS because this forms a boundary that may deter employees from accessing vital hazard information. This interpretation is consistent with OSHA’s notion of workers needing to have immediate access to chemical hazard information in the event of emergencies or when making safety judgments. 

For workplaces where workers move between several worksites throughout a work day, employers will have to make sure that SDS information is available instantly in case of an emergency. While SDSs can be stored at the main workplace location in these cases, employers will have to have someone present at all times to access this information within a few minutes. 

2. Electronic SDS Storage and Management

OSHA allows electronic storage and access to SDSs, acknowledging the pragmatic benefits of computer systems for handling large amounts of chemical data. Electronic SDS management systems, though, need to comply with certain requirements in order to meet the HazCom standard. 

When using electronic SDS systems, employers should ensure no impeding immediate access by employees is created. This requires that employees learn how to access the electronic system and reach specific SDS information in a timely manner. The system has to be incorporated into the overall written Hazard Communication Program, with definite procedures established for electronic SDS retrieval. 

One of the most important requirements for e-SDS systems is to provide sufficient backup systems in case of emergency. OSHA is aware that power interruptions, equipment failure, and delays in online access can happen, that might deny access to critical safety information. Employers are required to have backup systems that enable quick access to hazard data in such emergencies. Permissible backup resources are backup power systems, CD-ROM backup, or phone transmission of hazard data as a stopgap until the main system is back in action. 

Under emergency conditions of failure of the main electronic system, telephone transmission of hazard data is acceptable under OSHA rules as long as the actual SDS is transmitted to the site as quickly as possible. This telephone backup will only be acceptable for predictable failures of the electronic system, e.g., power outages or equipment breakdowns. In all other types of emergencies, the SDSs themselves need to be present, with telephone data acting as ancillary support. 

3. Mandatory SDS Content and Format Requirements

The HazCom standard requires that all SDSs conform to a standardized 16-section format, as outlined in Appendix D of 29 CFR 1910.1200. Such standardization provides uniformity across all chemical manufacturers and simplifies the easy location of vital information by workers. The mandatory sections are identification information, hazard identification, composition details, first-aid measures, fire-fighting measures, accidental release measures, handling and storage instructions, exposure controls and personal protection, physical and chemical properties, stability and reactivity information, toxicological information, and other applicable details. 

Sections 1 to 11 and Section 16 are required and must include all the required information. In case there is no relevant information for any subheading, the SDS shall prominently show that no relevant information is available. While Sections 12 to 15 could be provided to conform to the Globally Harmonized System (GHS), OSHA does not require these sections because they are under other agencies’ jurisdiction. 

All the SDS information has to be in English, with additional languages supported. The information must be found on scientific evidence applied to hazard classification, and the SDS preparers have to provide certain minimum information described in OSHA’s requirements. Chemicals manufacturers, importers, or employers developing SDSs need to make a revision to include newly available significant information about chemical hazards or protective measures within three months of learning of the same. 

4. Employer Obligations for SDS Acquiring and Updating

Employees are also responsible for procuring and updating SDSs. When chemicals arrive at the workplace without the relevant SDSs, it is the employers’ duty to procure these documents from the chemical manufacturer, distributor, or importer before applying the chemicals in the workplace. This obligation serves to ensure that no hazardous chemical is applied without adequate safety information at hand for the workers. 

The duty to carry up-to-date SDSs is continuous. Employers need to make sure that they have the latest versions of all SDSs and provide them to employees. When manufacturers revise SDSs with new hazard data, employers should actively request updated versions instead of waiting for automatic shipment since manufacturers need not automatically send updated SDSs to all past customers. 

For stored but not currently used chemicals, employers are also required to have SDSs and list these chemicals in their inventory of hazardous chemicals. The SDS requirement applies to all hazardous chemicals found in the workplace irrespective of how often they are used or whether they are stored or not.  

5. Incorporation with Written Hazard Communication Programs

SDS management cannot be a stand-alone affair but must be part of an overall written Hazard Communication Program. The written program shall identify individuals who are to obtain and maintain SDSs. The program shall describe where SDSs are kept in the facility and how access is provided to them by employees through either physical binders, computer systems, or combination methods. 

The written program should also explain procedures to be taken if an SDS is not received with a shipment of chemicals and define steps workers should take if they are unable to find an SDS. This structured method helps ensure that SDS management is integrated with other HazCom requirements, such as maintenance of chemical inventories, training employees, and labeling systems. 

6. Multi-Employer Workplace Considerations

In multi-employer facilities, SDS availability requirements get more complicated but stay strictly enforced. Each employer who has employees exposed to dangerous chemicals is required to have a written Hazard Communication Program, irrespective of which employer created the hazard. Employers are offered latitude in making decisions as to how SDS information is shared between different companies on the same site. 

No employer is required to physically keep SDSs with other employers but must notify them where SDSs will be kept, for example, at a general contractor’s trailer. The most important requirement is that all employees exposed have easy access to the SDS information they require, no matter who keeps actual documents. 

In addition to just having SDSs, employers are also responsible for ensuring that workers are trained on accessing and reading this information. Training involves instructing workers on the availability and location of SDSs, on how to acquire and utilize proper hazard information, and the specifics of the employer’s Hazard Communication Program. 

In the case of electronic SDS systems, employee training is especially crucial. Workers need to learn how to use the electronic system, search for chemicals, and access back-up systems when needed. This training must be hands-on and tested so employees really can find the information they need when they need it in the field. 

7. Hard Copy Access and Employee Rights

Even where electronic means are the default for SDS storage, workers have a right to ask for hard copies of SDSs. Employers should be in a position to supply printed copies on demand, especially in crisis situations where electronic access may not be possible. This mandate provides that workers will always have an avenue to get detailed chemical danger information regardless of technical constraints. 

The hard copy access provision also benefits emergency responders who can have instant access to SDS information during emergencies. Emergency responders and medical personnel need access to SDS information instantly in order to make effective treatment decisions. 

8. Recent Updates and Compliance Deadlines

OSHA’s 2024 revised HazCom standard has created new requirements impacting SDS content and format. The revised standard follows the UN’s 7th revision of the Globally Harmonized System, which includes added label requirements, enhanced trade secret disclosure, better hazard classification, and revised precautionary statements. 

Compliance timetables differ based on the chemical product type. Chemical substance manufacturers must revise their SDSs by January 19, 2026, while mixture manufacturers must revise their SDSs by July 19, 2027. Employers who utilize these chemicals have more time – by July 20, 2026, for substances and by January 19, 2028, for mixtures – to revise workplace hazard communications based on the revised information provided by suppliers. 

9. Enforcement and Penalties for Non-Compliance

Non-compliance with SDS availability and format provisions may lead to serious OSHA citations and fines. Compliance with SDS is viewed as a high priority by the agency as part of protecting workers, and infractions are not taken lightly during inspections. Employers need to audit their SDS management systems on a routine basis to maintain ongoing compliance with all provisions. 

The implications of poor SDS management are not limited to legal sanctions but also encompass greater risk of workplace accidents, possible liability in the event of an accident, and diminished emergency response capabilities. Effective SDS management is thus both a legal requirement and a sound practical necessity for ensuring workplace safety. 

10. Best Practices for SDS Management 

For complete compliance with OSHA’s requirements for SDS, employers must implement effective management systems that cover all details of the rule. This entails defining procedures for obtaining SDS, periodic review and revision of documents, training for workers on means of access, and keeping both primary and backup access systems. 

Daily auditing of SDS inventories against chemical inventories assists in the identification of coverage gaps and in ensuring that all necessary documentation is present. Employers should also make arrangements with SDS management service providers or develop in-house abilities for monitoring manufacturer revisions and ensuring the most up-to-date versions are always accessible to employees. 

The requirements under OSHA’s Hazard Communication Standard for SDS availability and formatting are an extensive system aimed at providing workers with instant access to key chemical safety data. Through the knowledge and implementation of these requirements step by step, employers can meet their legal responsibility and also establish safer working environments for all employees who could be exposed to harmful chemicals.
