SDSs must be readily accessible to employees during each work shift when they are in their work area. This accessibility may be accomplished in different ways. Some employers keep SDSs in a binder in a central location (e.g., in a pick-up truck on a construction site). Others, particularly in workplaces with large numbers of chemicals, provide access electronically. However, if access to SDSs is provided electronically, there must be an adequate back-up system in place in the event of a power outage, equipment failure, or other emergency involving the primary electronic system.
No matter what system is used, you must ensure that employees and medical personnel can immediately obtain the required information in an emergency.
