Munitions workers played a crucial role in the First World War. They supplied the troops at the front with the armaments and equipment they needed to fight. They also freed up men from the workforce to join the armed forces.
Following a shortage of shells in 1915, the Ministry of Munitions was founded to control Britain's output of war material. It oversaw all aspects of the production and supply of munitions, under the forceful and energetic Minister for Munitions, David Lloyd George.
A number of new initiatives were soon introduced to improve production levels. One of these was an appeal to women to register for war service work. Thousands of women volunteered as a result, and many of these were soon employed in the growing number of munitions factories across the country. By the end of the war, over 700,000 – and possibly up to one million – women had become ‘munitionettes’.
The munitionettes worked long hours in often hazardous conditions. Hear stories of some of the dangers and difficulties they faced by listening to these former munitions workers.
Becoming a Canary
Becoming a Canary
Munitions workers whose job was filling shells were prone to suffer from TNT poisoning. TNT stood for Trinitrotoluene – an explosive which turned the skin yellow of those who regularly came into contact with it. The munitions workers who were affected by this were commonly known as ‘canaries’ due to their bright yellow appearance.
Although the visible effects usually wore off, some women died from working with TNT, if they were exposed to it for a prolonged period.

As Ethel Dean, who worked at Woolwich Arsenal, recalled, ‘Everything that that powder touches goes yellow. All the girls’ faces were yellow, all round their mouths. They had their own canteen, in which everything was yellow that they touched… Everything they touched went yellow – chairs, tables, everything.’
'I was yellow, all over'
Health Hazards
Health Hazards
As well as handling the hazardous TNT powder, munitions workers risked their health in other ways in the busy, dangerous factories. The working conditions varied, but they often featured poor ventilation, exposure to harmful chemicals and sometimes even asbestos; and the physical labour involved – which included lifting heavy shells and operating machinery – could be back-breaking or extremely risky, as Caroline Rennies explains.

'I was never poisoned'
Noisy Conditions
Noisy Conditions
Depending on the type of production that was being carried out, the munitions factories could be very noisy working environments. With heavy machines operating, workers shouting at each other and moving heavy shells and equipment around, the factories were often deafening places to be. Thomas Peck described the munitions factory he worked at, Wright’s in Edgeware, Middlesex: ‘It was only a small place but the machinery, there was drills going and hammers and various things, you know. It was very noisy in there.

'You couldn't hear yourself speak'
Workplace Accidents
Workplace Accidents
Working as they did long before modern-day health and safety legislation, workplace accidents were not unusual for employees of the munitions factories. From relatively minor injuries to more serious incidents and even death, munitions workers risked their health and often their lives while carrying out their jobs.

The exact number of fatalities is difficult to know: many of these cases were kept out of the press, due to the impact such news would have had on national morale and the war effort. Isabella Clarkeremembered that her friend died from the effects of gas poisoning, contracted while they were filling gas shells at the White Lund munitions factory in Lancashire. Henry Oxley remembered from his time at Woolwich Arsenal, ‘Prevalent in my particular job was filings coming off the machine into one’s eyes. There was no protection to shield your eyes from the filings coming up. And that was an occurrence which happened quite often.’
'They were only slightly hurt'
Threat Of Explosion
Threat Of Explosion
There were a number of explosions at munitions factories during the First World War. The massive amount of explosive material kept at the factories meant this was an ever-present danger for those working at them. One of the largest of these disasters occurred at Silvertown, in London’s East End, in January 1917. As many as 73 people were killed, and 400 were injured. Florence Parsons, who was working nearby, remembered the huge sound the factory made as it went up: ‘A terrible explosion went. We thought it was a Zeppelin over the top of us – it really rocked us… Oh the explosion, it rocked everywhere.’ As key centres of war production, munitions factories were also particular targets for enemy air raids, adding another element of danger to working at them.

'There were two explosions'
Long Hours
Long Hours
The working day for a munitions worker varied according to where he or she was employed but, due to the pressures and demands of war production, they generally had to work long hours. Usually a shift system operated, and some workers also put in overtime. The length of time the shifts lasted were not standardised but could be up to 12 hours' long, as many factories operated both day and night. Many munitions workers later remembered how exhausting the night shifts were and the difficulty of staying alert when working them.

'It was all bed and work'
Short Breaks
Short Breaks
Despite such a tiring working day, munitions workers didn’t have many – or particularly long – breaks. Some even remembered having no breaks at all. The better factories provided canteens, washrooms and toilet facilities for their employees, but these were not to be found at every workplace. When Kathleen Gilbert was a munitions worker in London, her hours were, ‘from 6am to 5.30pm, standing all the time. We had a 10 minute break, to go to the toilets, and we had to stand and eat sandwiches at the machine.’

'We had ten minutes for tea'
Repetitive Work
Repetitive Work
Munitions workers carried out a wide range of jobs during the war, and were involved in the manufacturing of a variety of armaments and equipment essential to the war effort. They could be engaged in: cleaning, filling, painting and stacking shells; operating machinery; weighing powder; assembling detonators; filling bullets; lacquering fuses and making shell cases. It was often repetitive – but they had to stay focused, as their work was checked and needed to meet the required standards.

'Little springs, little this, little that'
Male Hostility
Male Hostility
At the start of the First World War, there were strict controls in Britain over the types of jobs that women could have. But the increasing need for more men in the armed forces meant that these had to be removed, so that women could take men’s places in the workplace. Although women were already able to work in factories, the types of jobs they carried out changed with the move from a peacetime to a wartime economy. There was often some resentment as women began to take over what was seen as traditionally ‘male’ work. Some of the 'munitionettes' experienced hostility from their male co-workers, and there was resistance to them earning the same wages as men.

'They didn't want to show us their livelihood'
Strict Rules
Strict Rules
Due to the risk of explosion at the factories, strict regulations were put in place to reduce the chances of accidents happening. The workers wore wooden clogs so as to avoid the sparks that could be caused by shoes with any metal in them. Other metal items were prohibited, including jewellery and hairpins. They were also not allowed to have any matches on them – something which cost Lilian Miles’s friend her job at the Coventry Ordnance Works when their fore-mistress saw a match drop out of her pocket. The girl was also imprisoned for this accidental crime: ‘She never got over it. Within a few months, she died. She was 20 years of age.’
