The series of these podcast is going to cover what machinery safety is, why it matters, how you can apply engineering solutions to solve problems while also keeping them safe and complaint with the relevant characteristics and requirements.
I have been in an engineering position, surrounded by machinery of some description since 1992, I have a strong background in electrical and mechanical engineering disciplines, and I have always had a curiosity to learn about engineering. I've studied it academically all the way up to degree, and post graduate level. I have travelled the far reaches of the globe and seen and assessed 1000's of machines in all different industries. I have consulted on the design following directives, regulations and standards on multimillion pound projects, and I still haven't learned everything there is to know. I think I will be an eternal student wanting to know more about machinery safety.
Machinery safety is a niche of general health and safety, and requires specialist knowledge to be able to apply it correctly. While occupational H&S safety concentrate on human behaviour, the management and safe systems of work, machinery safety deals with how that machine will manage the task it is being designed to do in a safe and reliable way. Its design should not to create any undue risk to the person using the machine. We all want a machine to be safe and not harm us or our friends and loved ones.
My aim is to share my experiences so that when you are faced with a scenario that will be discussed, in any one of the episodes, you will have the right steps to take. You might not, know the answer, but you will, have an idea on how to get to the right place, that is safe and compliant.
Health and Safety, but more specifically, machinery safety, is a learned skill, and with the right approach, framework and knowledge you will soon be on your way to making the right choices, if done correctly there is no need to fear or shy away from taking the first steps.

Where do I need to locate my emergency stops?
This podcast is going to cover, not just where to locate your emergency stops around your machines or on the machine itself, but what else you need to consider. This is will help make the decision process much easier, and you will at least have some clarity of what to think about, when you need to think about installing emergency stops on or around machines.

Description
Risk assessment for safety related parts of control systems, and how to approach those first decisions on what to do.
KEY TAKEAWAYS
This is an extra step, and builds on the information of the risk assessment, that you carried out at the beginning of the machine design.
This is not just for controls engineers, but for anyone who is involved with machinery, now has the ability and power to make a valuable input in the overall design of the safety related parts of the control system.

Description
The safety related part of the control system, is the brains, it's the intelligence, it's the part of your machine that will decide, if something is safe for you to interact with or not.
BEST MOMENTS
· 1 - Can they operate in the environment that you are using it?
· 2 - A fault in the hardware doesn’t create a hazardous situation.
· 3 - Errors in the control system logic do not lead to hazardous situations.
· 4 - Reasonably foreseeable human error during operation does not lead to hazardous situations.

Description
The work of someone who is interested in improving safety of machinery isn't one, where you identify an issue, report it and then it smoothly gets done with no resistance or pushback. - If only life was that straight forward.
KEY TAKEAWAYS
You will get opposition, and challenge, from curious questioning to outright disagreement and everything in between, sometimes from the same person in the same conversation.
BEST MOMENTS

Description
Once you've got hold of your maintenance manual, and the type of information you should expect to see contained within it
I'm going to cover the first 8 area's that you might expect to see in the manual, not all of it will apply to your machine, but it will give you a good indication of what to expect, and it is up to you to either provide it, if you are a manufacturer or request it, if you are the buyer of the machine. This episode has been made to serve both.
KEY TAKEAWAYS
· As a manufacturer you must state how the machine must be used, it sounds obvious, but you must state it, and be precise about the purpose of the machine.
· Once the operators are trained in the safe use of the machine, you can then think about what if any residual risks are around the machine.

Description
Machines operate in different modes, and there are key characteristics of changing these modes of operation if you want to ensure operator safety.
There are at least 4 key requirements that must be in place before, you change the mode of operation of a machine, and I'm going to cover them in more detail.
KEY TAKEAWAYS
When considering mode selection think about how are you going to disable the normal hazards and control the machine in a safe manner.
Remember that all 4 of these must be in place before you put it into service, this is not meant to be an order of priority but a means to help you remember the key requirements.
Think D.I.C.E.

Description
There are multiple types of emergency stops on the market and today, I want to discuss the over-use of shrouded emergency stops on installations, and where it’s inappropriate to install one.
KEY TAKEAWAYS
Location - can you change where it is, so that it does not get inadvertently knocked?
Alternative direction - to think about how it is mounted, and the way in which it is facing.
Size of pushbutton - can you change it to a smaller size so that it does not get knocked?
Type - can it be changed for a wire rope style or something equally suitable?

Description
This is going to be a deep dive into what a guard is, the required characteristics, the types, how to choose and where to get more information, for creating your guard design.
KEY TAKEAWAYS
Guards come in all sorts of shapes and sizes, and are defined as providing protection by a physical barrier, some are obvious and some are not so.
A guard doesn't necessarily have to be painted a certain colour, like red or yellow.
BEST MOMENTS
There are 6 key characteristics that all guards must have, without anyone of these it simply can't be classed as a guard.
Guard physical barrier, designed as part of the machine to provide protection
NOTE 1 A guard may act either
⎯ alone, in which case it is only effective when “closed” (for a movable guard) or
“securely held in place” (for a fixed guard), or
⎯ in conjunction with an interlocking device with or without guard locking, in which case protection is ensured whatever the position of the guard.

Description
How to approach hazards and apply the hierarchy of controls
KEY TAKEAWAYS
· When faced with a hazard on a machine, it is really important to know how to manage those hazards.
· However there are times when the machine cannot run slower or have forces that a below hazardous limits and for it to function as a machine due to commercial reasons.
BEST MOMENTS
· The last two of the hierarchy of controls are really the last resort to be used as a primary control but will often be used to enhance other control measures.
· The machinery directive or regulations uses the three step method, and the hierarchy of controls can be broken down

· There are 4 general principles when it comes to drafting instructions.
· Try and avoid technical jargon, by making the layout clear and easy to understand.
BEST MOMENTS
· Drafting information is a fundamental part of the design of the machine
