Legal check: Construction Vehicles and Mobile Plants]]> 14 Sat, 30 Jun 2012 10:18:32 +0000 http://forum.safebuild.co.za/index.php?threads/the-gmr2-1-appointee.580/ http://forum.safebuild.co.za/index.php?threads/the-gmr2-1-appointee.580/ invalid@example.com (Neil Enslin) Neil Enslin
One of the common denominator issues, along with section 16 and section 37(2), is General Machinery Regulation (GMR) 2. In particular the competency issue surrounding the appointment of the full time ‘employee’ who must be appointed in writing to oversee machinery for every premises where machinery is used.

The purpose of this newsletter is not to regurgitate the regulation, in particular the level of competency linked the KW formula. We have lived with...

Plant & Machinery Safety in Construction]]> Mon, 22 Aug 2011 07:52:27 +0000 http://forum.safebuild.co.za/index.php?threads/gas-cutting-backfires-and-flashbacks.460/ http://forum.safebuild.co.za/index.php?threads/gas-cutting-backfires-and-flashbacks.460/ invalid@example.com (Neil Enslin) Neil Enslin 1. Terminology:

The technical terms and descriptions of various malfunctions are:

(a) Backfire:

Flame enters into nozzle or torch with a violent popping sound. Flame either extinguishes or re-ignites at the nozzle.

(b) Sustained backfire:

Flame enters into nozzle or torch and continues burning inside with hissing or whistling noise.

(c) Flashback:

Flame enters into the torch and travels back into the supply system. The...

Gas Cutting: Backfires and flashbacks]]> Wed, 17 Aug 2011 08:53:43 +0000 http://forum.safebuild.co.za/index.php?threads/gas-cutting-maintenance-of-equipment-part-2.458/ http://forum.safebuild.co.za/index.php?threads/gas-cutting-maintenance-of-equipment-part-2.458/ invalid@example.com (Neil Enslin) Neil Enslin Cylinders:

Leaks round the valve spindle will be revealed by a hissing sound or a smell of gas. Tighten the gland nut and test with a leak detection spray, and if the cylinder continues to leak, return it to your supplier.

Nozzles:

Do not maltreat nozzles. The correct pre-heat flame and cutting oxygen stream can only be maintained when the edges of the gas orifices are sharp.
The orifices should be regularly cleaned with special nozzle cleaners. These are readily...

Regulators:

1. Cylinder pressure varies considerably with the different compressed gases. Be sure you select the correct regulator for the gas you are using. It is dangerous to use a Handigas regulator on an Acetylene cylinder, and similarly, it is dangerous to use an Acetylene regulator on a Hydrogen cylinder, etc.
