Welding of drums or other vessels – the potential for explosion

Lots of businesses which we visit have an oil drum or two lying around the workplace.  It may seems like a good idea to make use of one of these unwanted items and we’ve seen them made into bins and even barbecues.

However, depending on what used to be inside them cutting them open or welding something onto them can result in a powerful explosion.  If you want some more information of what we mean by this take a look at the video from WorkSafeBC; Drum Explodes During Welding, Killing Worker

The problem in this instance was that the original substance, acetone, a solvent used in the manufacture of fiberglass items and many other productions, remained in the vessel. Even a trace amount after the drum was washed through could still be present in sufficient quantity to create an explosive atmosphere. in the case of the video above this was less than a tea spoonful of the original acetone.

Looking at the safety aspects here you can see how likely it is that vapours will remain, even after washing out a drum.  Add into that the heat generated by cutting, grinding or welding the drum allowing the remaining substance to ‘gas off’ and you have a potential bomb on your hands.

The best route to reducing risk is to avoid this situation altogether but sometimes people do need to work in situations where welding will need to take place.  If you can’t avoid it then make yourself familiar with the best practices to reduce risk.

For more information please have a read through the free HSE guidance on the subject here;  Hot work on small tanks and drums INDG314(rev1)

Most importantly, consider if you really need to do this.  Replacing rather than repairing may be your better option.  If you do need to make repairs don’t forget that cold cutting or cold repair techniques may also be an option and will avoid the key risk of hot works and potential explosions.

Hand arm vibration (HAV) – are you really managing the risk?

All of us have our pet subjects.  Some of us do tend to bury our heads in the sand for areas in which we’re not as competent.  You may, if you are honest with yourself, have a hit list of subjects which you mean to ‘review’ at some stage.

Local IOSH groups or similar can be a really good place to start in tackling these issues.  Other professionals will have been there before and will have found out its really not as bad as you might think.

Once area we think you should look at afresh is controlling the risk from vibration.  We’ve been involved in assessments for many years now so if you need some help and advice just let us know.  If you’re still looking for that ‘good reason’ to make a start read the case below….

Company fined for failing to manage vibration risks

Newfield Fabrications Company, a manufacturer of steel components based in Cheshire, was fined £120,000 for failing to ensure that the risks to employees were adequately controlled.

Manchester and Salford Magistrates Court heard that in late 2015 the welder, who had worked at the company for several years, was given a job that involved a large amount of grinding and polishing.

After a few hours on the job, he began to experience numbness and tingling, commonly an indicator of exposure to high levels of vibration.  He asked to swap with another worker but he was told by his supervisor to carry on with the work.

A few weeks later, a 20 year old apprentice welder also began to suffer from vibration-related symptoms after using similar equipment.

An HSE investigation found that Newfield Fabrications failed to control employees’ exposure to hand arm vibration. The firm also failed to give its employees sufficient information, instruction and training on the effects of working with vibrating hand tools.

Newfield Fabrications pleaded guilty to breaching Regulations 6(1) and 8(1) of the Control of Vibration at Work Regulations.

According to the company’s accounts, it had a turnover of £7.7m in 2016 and made a pre-tax profit of £118,826.00 and so the £120,000.00 fine plus the £7241.00 costs is a significant sum for its Directors to find.

HSE inspector Helen Jones said:

“This is a case of the company failing to protect workers using vibrating tools. Exposure to hand arm vibration is a well-known risk which the company failed to adequately control.

“The company also failed to ensure workers were looked after when symptoms did arise leading to further exposure. This was wholly inadequate, and led to two employees suffering significant health effects.”

Construction deaths hit a record low

HSEIt’s great to be able to report some good news and I’m happy to be able to call it that.  We all qualify each improvement with an immediate caveat of ‘but many others still suffered death or injury which could have been avoided.  Lets not be afraid to say well done to everyone which helped drive these accidents down.

Its a very hard task to reach further improvements and yes, we do still have some way to go and we will get there.  For everyone which has put their time and trouble and resources behind driving down these risks – well done.

Health and safety statistics updated for 2017

Provisional data released by the Health and Safety Executive (HSE) reveals that 133 workers were fatally injured between April 2013 and March 2014, compared with 150 in 2012/13.

The overall rate of fatal injury has now dropped to 0.44 per 100,000 workers, compared to 0.51 in 2012/13.

Judith Hackitt, the HSE Chair, commented;

“The release of the annual statistics always leads to mixed emotions. Sadness for the loss of 133 lives, and sympathy for their families, friends and workmates, but also a sense of encouragement that we continue to make progress in reducing the toll of suffering.

“Whilst these are only provisional figures, they confirm Britain’s performance in health and safety as world class. For the last eight years we have consistently recorded one of the lowest rates of fatal injuries to workers among the leading industrial nations in Europe.”

Minister of State for Health and Safety, Mike Penning, said

“Any death at work is a death too many. But these statistics show that workplaces are getting safer.

“The Health and Safety Executive do an excellent job in making sure each and every one of us can go out to do an honest day’s work in the knowledge that our safety is being taken seriously.”

The new figures also show the rate of fatal injuries in several key industrial sectors:

  • There were 42 fatal injuries to workers in construction, lower than the average figure of 46. The latest rate of fatal injury is 1.98 per 100, 000 workers, compared to a five-year average of 2.07.
  • There were 27 fatal injuries to workers in agriculture, lower than the average of 33 for the previous five years. The rate of fatal injury in 2013/14 is 8.77, compared to the five-year average rate of 9.89.
  • There were 4 fatal injuries to workers in waste and recycling, lower than the average count of 7 over the last five years. The latest rate of 3.33 deaths per 100, 000 compares to an average rate of 5.48

In the last five years, the number of fatal injuries has fallen overall from 179 in 2009, to 147, 175, 171 to 150 in 2013.

Based on the latest available data, from 2011, Britain continues to have the lowest rate of fatal injuries to workers among the five leading industrial nations in Europe – Germany, France, Spain and Italy for the eighth year. Across Great Britain:

  • 106 fatal injuries in England were recorded – a rate of 0.41 deaths per 100,000 workers, compared to an average of 134 deaths in the past five years and a decrease from the 119 deaths (and rate of 0.47) recorded in 2012/13
  • 20 fatal injuries in Scotland were recorded – a rate of 0.78 deaths per 100,000 workers, compared to an average of 21 deaths in the past five years and a decrease from the 23 deaths (and rate of 0.90) recorded in 2012/13
  • 7 fatal injuries in Wales were recorded – a rate of 0.52 deaths per 100,000 workers, compared to an average of 10 deaths in the past five years and a decrease from the 8 deaths (and rate of 0.61) recorded in 2012/13

HSE has also today released the latest number of deaths from mesothelioma, a cancer caused by exposure to asbestos. These show that 2,535 people died in 2012, which is an increased from 2,291 in 2011.

Judith Hackitt said

“The high numbers of deaths relating to mesothelioma are a reminder of historically poor standards of workplace health and safety, which decades later are causing thousands of painful, untimely deaths each year. While we now recognise and are better positioned to manage such health risks, these statistics are a stark reminder of the importance of keeping health standards in the workplace on a par with those we apply to safety.”

HSE is due to launch an asbestos campaign in Autumn 2014 that aims to help at-risk tradespeople, such as roofers and builders, work more safely with asbestos to protect themselves from harm.

Highly flammable liquids fire burns spray booth operator

We have to be truthful and admit that we sometimes carry out tasks which in hindsight we could have done with far less risk.  It could be driving to work or what we do at home at the weekend away from the eyes of our colleagues and managers.

The case below highlights how susceptible we are to complacency.  We work with items everyday which carry with them great risks but we rarely suffer consequences for taking shortcuts. That in turn leads to greater and greater risk taking until an accident finally occurs.  Read the case below to find out what happened in this instance.

A paint manufacturing company in Manchester has been fined for health and safety failings after a worker suffered burns while trying to clean the floor of a spray booth.

Manchester Crown Court heard how an employee of HMG Paints Ltd was using a highly flammable solvent to clean the floor of a spray booth on site, a job he had done several times since the spray booth was installed.

After complaints about how difficult it was to remove the dried paint he was allowed to purchase an industrial floor scrubber to carry out the task. On 18 November 2014 electric motor on the floor scrubber ignited the cloud of flammable vapour that had built up in the spray booth.

The employee was seriously injured, receiving 26% burns, and was treated at the specialist burns unit at Wythenshawe Hospital.

An investigation by the Health and Safety Executive (HSE) found that the planning for cleaning floors using solvent failed to recognise the hazards and level of risk associated with the use of highly flammable solvents to clean floors. The employee who was injured had not been trained to clean floors and was not adequately supervised when carrying out the cleaning activity.

HMG Paints Limited, of Collyhurst Road, Manchester, pleaded guilty to breaching Section 2 of the Health and Safety at Work Act 1974, and was fined £80,000 and ordered to pay costs of £39,669.40.

Speaking after the case HSE inspector David Myrtle said:

“This is a company that handles large quantities of flammable solvent, the hazards are well known and the company has a duty to control the risks arising from the hazards.

“It was custom and practice to clean floors using highly flammable solvents applied using a mop and bucket. In this instance the company failed to adequately control the risks and an employee was seriously injured.” [source HSE]

Oxygen explosion causes worker severe injury and costs firm £1m fine

Oxygen is used throughout many sectors of industry and healthcare.  This common element can be taken for granted as we are so familiar with its name and its use.

Are you aware that;

  1. increasing the concentration of oxygen in air from its normal 21% to just 24% can make an enormous difference  in how easily items will catch light;
  2. They will also be far harder to put out once they are burning and will burn much more fiercely;
  3. Oxygen which is pure and at high pressure (from a cylinder or supply line for example) can react spontaneously with oils, greases and other materials causing them to catch light;
  4. Nearly all materials including textiles, rubber and even metals will burn vigorously in the presence of pure oxygen.

More information on all of the above and the correct precautions which must be in place can be found here; http://www.hse.gov.uk/pubns/indg459.pdf

Below is an accident which illustrates the dangers of bad practices around oxygen.  If you need helps and support on these and other issues please do contact us for more information.

Case Law: Oxygen Pipe Explosion

Sheffield Crown court heard that work was carried out by an in-house contractor to fit a valve to an oxygen pipe that carried 99.9 per cent pure oxygen in August 2013

The worker was checking the work when he heard hissing from the valve. When investigating the noise, the pipe and valve erupted in flames causing the person to suffer 60- 70 per cent burns.

As a result of the severe injuries he suffered he was initially not expected to survive and underwent several skin grafts whilst being kept in a coma for several weeks.

A Health and Safety Executive (HSE) investigation found that the oxygen pipe had been fitted with contaminated second-hand flanges and butterfly valves containing materials unsuitable for use with oxygen.

Sheffield Forgemasters Engineering Limited of Brightside Lane, Sheffield pleaded guilty to breaching Section 2(1) of the Health and Safety at Work Act 1974 and were fined £1,000,000 with £58,000 costs.

After the hearing, HSE inspector Carol Downes commented: “This incident could so easily have been avoided by simple carrying out correct control measure and safe work practices.

“Companies should be aware that HSE will not hesitate to take appropriate enforcement action against those that fall below the required standard.”

What’s the best way to move gas cylinders?

Moving gas cylinders in your workplace – the hazards

We see gas cylinders in use across the wide range of clients we visit.  Some will use cylinders to power their MHE (Materials Handling Equipment) and some will be using gases to complete welding and cutting operations as part of their production process.

We’ve written blogs in the past about cylinders and safety measures but not about their actual handling (see here for an accident linked to this post).

To lift or not to lift; that is the question

The key issue with cylinders and their movement relates to handling and lifting.  Many workplaces are equipped with various handling equipment and its tempting to use one of a number of means to lift cylinders.  It’s also quite tempting to manually handle cylinders into position when the distances aren’t too great.

The risks of lifting cylinders

We’ve seen in real life a number of situations where a high risk method has been used to move cylinders, check through the examples below and see if you recognise any of these from your past experience of perhaps even your own site;

  1. Manual handling by churning (rolling on the base);
    1. This is a valid method but what about tall and heavy cylinders and moving them through a cluttered and busy workplace? One drop can cause significant damage to the cylinder, or even the valve, creating a ballistic missile capable of passing through walls!  The is suitable for short movements of easily handled cylinders only (<5m).
  2. Lifting using fork lift truck attachments;
    1. This is fine if the cylinders are safely stored on a pallet or cradle but using attachments such as barrel clamps, scissor clamps or magnets – this can damage the cylinder walls with catastrophic consequences.
  3. Lifting using the valve shroud or valve itself;
    1. Lifting on the valve shroud can cause it to detach from the cylinder, it’s just not designed for a suspension lift.
    2. Lifting on the valve it certainly a very bad idea – again, its not designed for this and could lead to leaks, sudden failure and may of course slip from the lifting sling – this is the highest risk and must always be avoided.

What should you do?

In simple terms follow the guidance  issued by the BCGA, which you can download here; BCGA TIS 28

If you still have questions perhaps now is a good time to ask an experienced consultant from Outsource Safety to review your current procedures.  We can visit and carry out specific risk assessments or even a comprehensive Gap Analysis in line with the requirements of the internationally recognised Management Standard OHSAS18001, contact us for more information.

Spa Pools; new legislation for commercial installations

You might be wondering why this post is here, if you are you’re probably not aware of the wide range of clients which we work with!

This post relates to the commercial rather than residential use of these spa’s but if you’re lucky enough to have one at home there are some good points below which are worth being aware of linked to HSE document HSG282 “Control of legionella and other infectious agents in spa-pool systems” published in January 2017.

The simple facts are that these warm agitated pools of water provide a good breeding ground for a number of harmful bacteria; folliculitis, e-coli, viral skin infections and of course legionella.  Add to this the risk of droplet inhalation through agitation and the risk increases significantly.

The key risk is that water in these pools is kept at a steady 30-40oC, an ideal temperature for these bacteria to breed in, but don’t forget the other key associated risks such as;

  • chemical exposure;
  • electrical risks;
  • slipping;
  • entrapment;
  • drowning and so on.

If you have any of this equipment in use or plan to install it take the time to read through this useful guidance, a copy can be down loaded here:  Control of legionella and other infectious agents in spa-pool systems HSG282 (HSE)

If you’re a user of such equipment ask your hotel or operator if water is changed between rental groups as required by this guidance and check that a robust in line disinfectant feeder has been installed as you cannot rely on direct chemical dosing through tablets.

Occupational Health Risks of Working in the Sun (UV) Rays

What are your legal obligations as an employer?

The Health and Safety at Work Act makes it clear that there is a legal duty on every employer to ensure, as far as reasonably practical, the health of their employees.

It also says that employers must provide “information, instruction, training and supervision” to ensure their safety.

The management of Health and Work Regulations also require the employer to conduct a suitable risk assessment of the risks to the health of their workforce. This includes the risks from UV radiation.

Did you know?

  • Skin cancer is the most common cancer in the world
  • Rates of skin cancer are increasing faster than any other cancer in the UK
  • 90% of skin cancer deaths could be prevented
  • 2/3 of construction workers are outside for 7 hours per day
  • Outdoor workers have a higher than average risk of developing skin cancer
  • 100% of UVA rays pass through clouds so sun protection is essential, even on cloudy days

How can you reduce the risks associated with Ultraviolet (UV) Rays in your workforce?

  • Conduct a risk assessment and communicate that risk assessment and the control measures to the workforce;
  • Issue guidance on those control measures which will include using sunblock, re-hydrating and appropriate clothing;
  • Carry out a safety briefing/toolbox talk with all staff explaining the health risks associated with exposure to UV Rays;
  • Don’t forget the sign-off sheet to demonstrate understanding from the workforce and evidence that you have communicated health risks to the workforce

Don’t forget the drivers!

Most glass used for windows blocks UVB but not UVA rays.

A person sitting in a vehicle can still receive significant exposure to solar UVR. There are many different types of glass: each provides very different levels of sun protection. Therefore drivers may also be at risk as glass do not block all UV radiation.

Public Tip Off leads to Prosecution and £52,000 fine

HSE often attends sites which have been reported as dangerous by members of the public.  In fact, we hear of these visits quite regularly and they can be as a result of genuine concerns or perhaps as a result of noise, dust and other disturbances causes nuisance to neighbours.

The case below relates to a North London site at which safety management and edge protection were sadly lacking.  Malik Contractors and Engineers Ltd were fined a total of £52,000  plus £4,415 costs after pleading guilty under Reg 13(1) of The Construction Design and Management Regulations 2015.

In response to concerns from members of the public HSE carried out three separate inspections and each time found numerous breaches of health and safety legislation. These included electrical systems, unsafe work at height and no fire detection of fire fighting equipment despite workers sleeping on site.

 

 

 

 

HSE inspector David King commented:

“This case highlights the importance complying with enforcement action. Duty holders have the responsibility to provide their workers with appropriate training and equipment so they can work safely. In this case Malik Contractors failed to do so.

It is essential those responsible for construction work understand they are also responsible for the health and safety of those on and around the construction site, and ensure suitable and sufficient arrangements are in place to plan.”
