Afterthoughts on Safety
(Continued from page 28)
A few years ago it didn't bother me to jump across a 42" trench carrying a piece of pipe. (What the heck is an inguinal hernia?) Since we were only going to use the scaffold for one day, I never thought that hammer would slip off and hit anyone. (I had the feeling that the toeboard should have been nailed on.) You know that rule about a tool rest on a grinder always being V-inch from the wheel. It can't possibly make a difference for another 14-inch. (I sure was lucky when that chisel became wedged and the wheel exploded into a thousand pieces.) Everyone knows you can exceed the rated capacity of a crane since a safety factor is built in. (Wonder if the boss is going to take the cost of a new boom out of my hide?) Making that ladder out of scrap lumber sure saved us a bundle. (Hope those guys that were on the ladder when it broke aren't hurt too bad.)

The 11-year-old Kaiser Building gets a face-lift. Here a two-man crew starts its drop, spraying water on the exposed rock panels to remove dirt loosened by the fluoride salt solution. The crew was in constant radio communication with the foreman on top of the building.
New Method Used to Clean a Highrise
The tallest exposed aggregate walls ever used for an office building have had a face-lifting, cleaning and coating job after eleven years exposure to the sun, wind and periodic smog of downtown Oakland, Calif.
The curving, 28-story Kaiser Building at the head of Lake Merritt has three full faces of precast rock aggregate. The north face reaches 395 ft. above the sidewalk and overlooks a 32-acre, tree and flower-bedecked roof garden and pool on top of the adjacent Kaiser garage.
The two other aggregate panels face east and west. Each is 349 ft. high and start 16 ft. above the ground. All panels are 58-ft. wide by 10-ft. high to 5½ ft. by 15 ft. welded by imbedded studs to the steel framework.
The exposed aggregate has weathered well in the mild climate. Cleaning was in order when Kaiser Center, Inc. decided to remove "Kaiser Center" signs of illuminated letters on the east and west walls since they did not conform to present overall Kaiser logotype design.
After testing a 15-ft. high by 58-ft. wide section, the cleaning method consisted of a solution of buffered fluoride salts, which tends to harden the stone in much the same way a fluoride toothpaste works on teeth. This is the first basic new development in building cleaning in over a century.
BUSINESS JUNKETS WILL GET FAR MORE SCRUTINY, Internal Revenue says. In a recent statement, IRS issued a clear warning against alleged abuses. As IRS sees it, too many people are claiming deductions for conventions regarded as vacations in disguise. Only a short time is spent on business. IRS will determine the "primary purpose" of a trip, depending on all facts. But a key factor is the relative time spent on business versus pleasure.
