When
did you last inspect your safety light curtains? - Companies using light
curtains to safeguard machinery often do not appreciate the implications of the
regulatory requirement for inspections.
How
functional safety helps to save lives
-In this article Ron Bell explains functional safety and
looks ahead to the revision of the IEC 61508standard that is due for publication
in 2010.This article by Jeanne Erdmann was first published in the January 2008
edition of the IEC's E-TECH. http://www.iec.ch
Changes
to European categories of safety control will come to Australia in due course
- The basis of AS 4024-1501 safety related parts of control
systems defines categories of control system design which become more fault
resistant as the risk increases. This is changing in Europe with the adoption of
EN-ISO 13849-2006, which replaces the categories defined in EN 954-1 (which is
AS 4024-1501) with Performance Levels and will be fully adopted in Europe by end
of November 2009.
Risk
assessment still vital under new Victorian regulations -
The new Victorian Occupational Health and Safety Regulations are designed to
simplify safety but, in the case of risk assessments, their release has caused
real confusion.
Pilz have vast experience in this area, this can be seen from the following papers hosted by industry search.com.au:
Mining
faces growing pressure to address plant hazards Part
One and Two
- With a fatality rate double the national average and an injury
rate that is 50 per cent higher, mining is a dangerous industry. The causes of
this extraordinary injury rate are equally as remarkable: machinery and plant
accounted for 75 per cent and two in every three mining injuries were put down
to bad design, far more than the 50 per cent the manufacturing sector attributes
to design. Part 2 considers
what can be done to make mining plant safe and compliant.
Not
all e-stops are equal before the law – how to be sure yours comply -
Because emergency stop devices or “e-stops” are everywhere, they tend to be
taken for granted but the law takes them very seriously as the last line of
defence in machine safety-Australian Standard 4024
describes an emergency stop as “a device which, regardless of the power
source, e.g. electrical pneumatic or hydraulic, requires deliberate action to
bring a machine to rest when danger is recognised”. Pilz
Safe Automation's Frank Schrever explains the basics of how the Plant
Regulations and the Australian Standard for safeguarding of machinery apply to
emergency stop devices.
SafetyBUS
p - This is the first open, safe bus system to have been
approved by BG to category 4 in accordance with EN 954-1, EN 60204, EN 62061 and
by TÜV to AK 6 in accordance with DIN V 19 250, SIL 3 in accordance with EN IEC
61508 and NFPA 79. This guarantees a wide application area for safety
applications, from which users in plant and machine engineering as well as the
automotive industry can benefit.
Pilz
Safety PLC delivers uncompromising safety at new Darwin fuel terminal -With
up to 113 million litres of highly flammable fuels on site, the new Darwin
Industry Fuel Terminal's operators selected a highly specified Pilz Programmable
Safety System to oversee a very basic yet critical device: the emergency stop.
Pig tamed: Pilz safety system monitors 119 wine paths at Wolf Blass - A silicone pig sweeps through the lines at Wolf Blass, entering a ‘key station’ where winery staff must choose one of 119 paths. When it comes to safety, nothing has been left to chance – each path is safeguarded with a Pilz safety switch and the entire battery of switches is monitored by a Pilz Programmable Safety System (PSS).
Pilz PSS tame synchrotron’s silent hazards travelling at the speed of light - A safety challenge like no other in Australia. The newest and biggest piece of scientific equipment built here is just that - the Australian Synchrotron shoots electrons around its 216 metre circumference in just 720.5 nano seconds.
Safeguards at Australia's nuclear reactor world's best -when the world's most brilliant scientists use a new Australian Nuclear Science and Technology Organisation (ANSTO) experimental facility, they will be protected from radiation exposure by a meticulously designed network of Pilz Programmable Safety Systems (PSS).
Designers, manufacturers, importers, suppliers all face safety laws- For years, employers have been in the spotlight when it comes to the enforcement of workplace safety, but as regulators begin to look further up the supply chain, designers, manufacturers and suppliers are coming under pressure.
Much more than guarding, safety is all in the design- An article by Frank Schrever of Pilz
Mechanical
safety switches easy to install, hard to defeat -Category
4 compatible mechanical safety switches that, when used with Pilz control
systems, can prevent access until an area is safe.
AS4024 vs. AS61508 - Just as Australian industry comes to grips with safety standard AS4024, a newer, more complex, international and now also an Australian standard is gaining wider usage.
Productive safety - Only a safety system that enhances a line’s productivity is truly safe, according to Pilz Safe Automation.
Why everyone’s talking about safety - Occupational health and safety (OHS) seems to be on the lips of every engineer around the world today, and for good reason – the sheer number of work related deaths is still shocking at an estimated 2,256,335 workers per year. The annual injury rate must be in the hundreds of millions.
Laws, Standards and Approvals: Exploring the compliance jungle- When a machine is said to be “approved” or meets a particular design standard, sometimes the claim is misleading or irrelevant, but may actually hint at a legal necessity.
108 year old machine made safe with new millennium Pilz systems- Bringing mining machinery from the 1800s up to 21st century safety standards is not easy, but the challenge has been met with electronic technology from Pilz.
Lockwood makes massive savings with Pilz safety refit - Dating from 1916, the key coining machines at Lockwood’s Oakleigh factory were not built to modern safety standards, but digital safety technology from Pilz has given them a new lease of life.
Separation of safety bus and standard bus- Productivity gains often go hand in hand with today’s fast, efficient safety technology. Safety PLCs such as the Pilz PSS Programmable Safety Systems and the safe bus system SafetyBUS p bring the engineer a whole new battery of tools to smooth production
Guide

download in excess of 5Meg but it is worth the wait! This guide
covers:
- Programmable Electronic Systems in Safety-related

This A5-sized book runs to more than 200 pages and
will be of interest to engineers and managers concerned with the safety
of machinery and processes. Pilz has prepared the guide in response to
the growing importance of electrical, electronic, and programmable
electronic safety-related systems, and the increasing expectation of
executive bodies requiring companies to comply with the principles and
procedures of IEC 61508 (the series of standards for the functional
safety of E/E/PES safety-related systems). It is thought that there is
no other comparable publication that covers the topic in such detail,
providing theoretical and practical advice and guidance on how to comply
with the relevant legislation.
