Special Information:                              May form combustible concentrations in air. Risk of dust explosion.

Section 6: Accidental Release Measures

Personal Precautions:                           See Section 8 for PPE information. Do not breathe dust. Do not ingest.

Emergency Procedures:                       Cover spilled materials to prevent dispersal by wind.

Environmental Precautions:                 Do not allow spill materials to enter storm drains or surface waterways.

Containment and Clean-up:                  Take up mechanically and place into containers for proper disposal.

Section 7: Handling and Storage

Handling:                                   Wear personal protective equipment (PPE) such as normal work clothing, a tight fitting dust nuisance mask, chemical resistant gloves and goggles or safety glasses. Refer to Section 8 for PPE information. Wash thoroughly after handling. Avoid contact with skin, eyes and clothing. Avoid ingestion and inhalation. Do not eat, drink or smoke while handling. After handling, use good hygiene before eating, drinking, smoking or using the bathroom.

Storage:                                     Store in sealed packaging in a dry, ventilated location. Keep away from sparks and flame.

Incompatibilities:                      Air dust concentrations may become combustible or explosive.

Section 8: Exposure Controls / Personal Protection Equipment [PPE]

Engineering Controls:              Use with adequate ventilation.

Personal Protection Equipment [PPE]

            Respiratory:                 Under ordinary conditions, use of a well fitting dust nuisance mask is recommended. Wear a NIOSH approved respirator, well fitted and in good condition when exposure to dust levels above exposure limits.

            Eye Protection:            Wear ANSI approved safety glasses or goggles when handling dry or wet product to prevent contact with eyes. Wearing contact lenses is not recommended when working with concrete.

            Skin Protection:           Wear chemical resistant gloves, rubber boots and clothing impervious to water to protect skin from both dry and wet product. Wear suitable work clothing. Do not solely use barrier creams for skin protection. Remove clothing that becomes wet from contact. Immediately wash exposed skin.

Section 16: Other Information

Employers Responsibility: Employers must ensure that the SDSs are readily accessible to employees for all hazardous chemicals in their workplace. This may be done in many ways. For example, employers may keep the SDSs in a binder or on computers as long as the employees have immediate access to the information without leaving their work area when needed and a back-up is available for rapid access to the SDS in the case of a power outage or other emergency. Furthermore, employers may want to designate a person(s) responsible for obtaining and maintaining the SDSs. If the employer does not have an SDS, the employer or designated person(s) should contact the manufacturer to obtain one.
