Perlite loose-fill insulation fills the voids and keeps the comfort in.
CAVITY WALL
CONCRETE BLOCK WALL
Perlite loose-fill insulation is an inorganic, nonasbestos inert mineral expanded by a special heat process and treated with a nonflammable silicone. The resultant lightweight, granular product handles and pours easily and provides a quick, inexpensive and permanent method of efficiently insulating masonry walls. Heat transmission may be reduced 50% or more when perlite loose-fill insulation is used in the hollow cores of concrete block or cavity-type masonry walls. The 2 hour fire rating of an 8 inch concrete block is improved to 4 hours when cores are filled with silicone treated perlite.
Perlite loose-fill insulation is free-flowing and completely fills all voids, including the spaces between mortar joints, without bridging. Installation costs are significantly reduced because the lightweight material pours easily, quickly and special equipment or skills are not needed.
Perlite loose-fill insulation is rot, vermin and termite proof and noncombustible. In addition, as settling is insignificant, perlite loose-fill insulation is as permanent as masonry walls themselves.
Perlite loose-fill insulation is silicone treated to assure low water retention and low wicking action for increased insulating efficiency.

38 MASONRY/FEBRUARY, 1980
Employers Reminded of OSHA February Posting Requirement
During February, firms with 11 or more employees are required to post the total count of job-related injuries and illnesses that occurred in their establishments in 1979, the Occupational Safety & Health Administration is reminding employers.
To fulfill the requirement, employers need only post the last page or right-hand portion of OSHA Form 200, "Log and Summary of Occupational Injuries and Illnesses." The form must be posted by February 1, 1980, in the place or places where notices to employees are customarily posted, and must remain in place until March 1, 1980.
Even if there were no job injuries and illnesses during 1979, zeros should be entered on the totals line, and the form posted. The person responsible for preparing the annual summary should certify the totals are correct and sign the form.
Firms must also notify employees who move from worksite to worksite, such as construction workers, and employees who do not report to any fixed establishment on a regular basis. Employers must give a copy of the summary to any of these employees who are on the payroll during February.
Employers with 10 or fewer employees are exempt from the February posting requirement. They are also exempt from other OSHA recordkeeping rules, unless they are selected by the Labor Department's Bureau of Labor Statistics for a statistical survey or are subject to certain state recordkeeping regulations. However, all employers are required to report within 48 hours to the nearest OSHA office all accidents which result in one or more fatalities or in hospitalization of five or more employees. OSHA is now considering reducing the reporting time to 8 hours.
