New
Abrasive Metering Valve Shows What Matters
The
days of open abrasive blasting, with minimally trained operators
using loads of cheap abrasive are dwindling
in the United States. Environmental, safety, and health regulations,
combined with demanding surface profile requirements, mean
that abrasive blasting is often being performed in containment
by skilled operators using higher priced media. As contractors
work to control their costs in this new work environment, they
need to find ways to improve labor productivity. Carefully
managing their abrasive consumption is one key to maximizing
blasting productivity. Axxiom Manufacturing Inc. has introduced
a new abrasive metering valve, a small piece of equipment designed
to make a big difference in productivity.

OSHA Issues
New Workplace Rule on Chromium
The Labor Department reduced the acceptable levels
of workplace exposure Monday to a cancer-causing metal, hexavalent
chromium, but critics said the new standard still leaves thousands
of workers at risk.
The new rule limits worker exposure to the carcinogenic metal to no more than
5 micrograms per cubic meter of air, a large reduction from the old standard,
but also a level five times higher than what had been proposed by the agency
two years ago. The old standard, issued in 1971, was 52 micrograms per cubic
meter of air.

A Primer
on Welding Smoke and Fume Control
Welders, health organizations and management
are all becoming increasingly concerned with the effects
of welding smoke and fumes in the work place. In addition, management is becoming increasingly conscious
of the costs of absenteeism and reduced productivity
resulting from illness caused by polluted air. There
is little doubt that welding is one of the leading causes of
in-plant air pollution in industry. However, many companies
are still unaware of the potential health risks inherent in
welding, nor are they aware of the unnecessary expenses incurred with many common control systems.

How to Create an Abrasive Blast Room
The design criteria required for a properly sized
blast room system includes the size of the largest workpiece,
the weight of the largest workpiece, the material handling method,
the number of hours of blasting per day, and the base material
of the workpiece. Each of these items needs to be addressed in
order to finalize the configuration of the blast room.
The size of the largest piece will determine the dimensions
of the blast room enclosure. The width of the room is determined
by adding four to five feet on each side of the workpiece.
This space is required for the blast operator to maneuver
around the part and blast the part from various angles....
