The Belden Brick Company considers our product an "article" as defined in 29 CFR Part 1200 (b)(5)(iv) and 40 CFR Part 372.38. As an article, an SDS is not required and the product is exempt from all other requirements of the hazardous communication standard. OSHA requires a Safety Data Sheet (SDS) for brick since it is occasionally dry sawed.

INSTALLATION
Joint Thickness and Mortar Type:
Grout and mortar for joints in brick, and mortar for bedding brick as well as chemical resistant membranes must be selected to meet anticipated corrosive and thermal conditions. The recommendations of the grout or mortar manufacturer must be obtained to positively establish the chemical and thermal resistance of a particular flooring system.

Expansion and Contraction Joints:
Movement occurs in brick floors due to contraction of concrete, mortars and grouts; expansion due to heat and the growth of the ceramic materials, and differential movements between walls, floors, columns and other building elements. The movements in chemical resistant/industrial floors cannot be predicted with precision. Practices developed from experience coupled with standard control methods must be utilized in designing compensation for movement. Joint sealants used must be chemically resistant, elastic and bond extremely well with the brick. In chemically resistant floors polyethylene foam backer rods are recommended.

Method:
Bricklaying techniques should be in accordance with the chemically-resistant grout/mortar manufacturer's directions.

Cleaning:
Chemically resistant/industrial floor brick are available with a factory applied film of melted paraffin wax. Care in handling pre-waxed floor brick must be taken to avoid stacking brick at the job with a waxed surface contacting an unwaxed surface. After all joints have hardened, steam cleaning is used to melt the wax and remove any grout/mortar residue from the finished flooring surface.

AVAILABILITY AND COST
Availability:
Available in all 50 states, Canada and for export.

Cost:
Installed costs will vary by types of units, floor membrane and mortar requirements, types of construction, location of project and local bidding practices. Cost information for a particular project and application can be obtained from authorized distributors in the individual project area.

MAINTENANCE
Cleaning procedures must be determined prior to the selection of the chemically resistant brick/mortar flooring system. Cleaning compound such as phosphoric acid, trisodium phosphate, sodium hypochlorite and chlorine, bromine or iodine- releasing agents may attach the flooring materials. The chemically resistant mortar/grout manufacturer should be contacted at the planning stage in order to make recommendations for a flooring system which will be compatible with the individual plant's maintenance practices.

Expansion and Contraction Joints:
Expansion joints should be inspected frequently as part of a normal maintenance program. Sealants and back-up foam rods are limited life materials and must be replaced at the first sign of deterioration in order to prevent corrosive reagents from penetrating and undermining the chemically resistant brick floor.
