UAE doctors urge cautions after the end of Midday Break

Doctors warn it is imperative for labourers to take precautions when working outside in the heat, with the midday break rule no longer in effect. Yesterday was the last day this year that companies were required to give workers two and a half hours off in the heat of the day.

But with temperatures verging on 40°C forecast for the rest of the week, heat-related health problems still pose a very real hazard for the workers, many of whom are required to work long hours outside in heavy clothing.

Ideally, labourers should still be allowed at least a one-hour break at midday, said Dr Ahmed Bahaa, a general practitioner at Burjeel Hospital.

"The weather here is very hot and it's dangerous to work outside, particularly around midday," Dr Bahaa said. "Between 11am and 3pm are the hottest times."

He said breaks were particularly important when temperatures exceeded 45°C.

"Workers should drink a lot of cold fluids too," Dr Bahaa said. "Every hour, or hour and a half, they should take a rest for 15 or 20 minutes in a cool place."

Those who fail to take such precautions will suffer and could even die, he warned.

"With mild symptoms, they will have head cramps and will sweat profusely. With moderate symptoms, they will have a headache, may start vomiting, develop heat exhaustion or have palpitations."

For those who are not treated promptly and properly, even more severe symptoms may include heat stroke, coma and death. Death becomes likely when body temperature exceeds 41°C, said Dr Bahaa.

Humidity also a huge effect on nutrient loss, said Dr Tarek Azeem, consultant of internal medicine and an endocrinologist at Al Noor Hospital.

"When it's hot and humid, they lose a lot of sweat, water and electrolytes," Dr Azeem said. "There is a part of the brain called the hypothalamus, which contains the hypothalamic thermoregulator control mechanism.

"This reacts to the change in environmental temperature and adjusts the body temperature in extreme heat and cold."

In extreme heat, especially with humidity, people need to help their body adjust to the temperature by taking breaks, drinking water and keeping cool, he said.

Failing to do so could lead to heat-related disorders including heat stroke, which could lead to convulsions.

"We should not let these people work outdoors in this temperature for long periods of time," Dr Azeem said.

"They must take breaks, ideally between 11am and 3pm, even if it's just one hour like between 12pm and 1pm.

"They must also drink lots of water, not wear heavy clothes, take lots of shade, and if they have diseases like hypertension, diabetes, epilepsy and others, they should not be allowed to do such type of work because this increases the risk of heat-related disorders."

Another doctor, who works at a private medical centre for workers, said this summer he saw up to 10 cases of dehydration and two of tetany, or muscular spasms caused by low calcium levels, a day.

Workers can develop the condition if they spend too much time in the sun, perspiring while not replenishing lost nutrients. It can lead to leg cramps and "clawing" of the hands, he said.

"We give them a 1,000 to 1,500cc intravenous drop of calcium, magnesium, potassium, salts and other nutrients, and then they're OK," the doctor said.

Some of his patients said their companies did not give the mandatory breaks, and companies have been accused of failing to provide adequate health care, conditions, water and nutrition.

"The Government, the municipality and leadership are so nice. They show so much respect and have set such kind rules for the labourers, but some companies do not follow them," said the doctor.

The midday break was introduced in 2005 for workers at uncovered building sites. Labourers were initially given a break from 12.30pm to 4pm off in July, August and September. The break was shortened in 2006 so that it ended at 3pm. Last summer, more than 50,000 worksite inspections found only 109 breaches.




Midday break inspections continue in UAE

gulfnews.com - ‎Jul 28, 2013‎ Dubai: The Ministry of Labour confirmed that 99.41 per cent of establishments nationwide were found to be complying with the midday break decision within the first two weeks after its issuance.

According to this decision which came into force on June 15 and will continue until mid-September, workers shall get a break every day between 12.30pm and 3pm.
According to Maher Al Ouwaid, Assistant Undersecretary at the ministry's inspection affairs department, since the beginning of the implementation of the decision, a total of 25,248 inspection visits were made nationwide to different companies to inspect the implementation of the midday break.

Also, 17,296 guidance visits were made in the early morning hours by labour office officers across the country. The aim of these visits is to make both workers and employers aware of the importance of applying this decision and the dangers of heat stress which workers may suffer due to carrying out their work in strong sunlight. He said a total of 25,100 establishment across the country showed adherence to the law which comprise 99.41 per cent of the companies.

"A total of 148 companies nationwide were fined for breaking the midday break rules," said Al Ouwaid.

Al Ouwaid added that under the directives of the Minister of Labour, Saqr Gobash, the daily inspection campaigns conducted by the ministry are aimed at making employers aware of the importance of the midday break decision as it ensures the interests of both workers and employers and provides protection for workers in accordance with national legislations, a matter which could contribute to increasing production and achieving efficiency in performance.

He said that 4,865 inspection visits were made in Dubai, 2,519 in Ras Al Khaimah, 5,828 in Sharjah, 2,508 in Ajman, 1,255 in Umm Al Quwain and 1,798 in Al Fujairah.
Additionally, the Ministry of Labour has already carried out 976 visits in the Western Region, 3,165 in Abu Dhabi and 2,274 in Al Ain.

"We have a total of 18 inspection teams who regularly visit worksites and ensure that the rules set by the ministry are being followed, including providing workers with shaded areas to rest during the break as well as professional safety tools to protect labourers from work-related injuries, dehydration and other health risks such as sunstroke and heat exhaustion," he added.

Companies found breaking the midday rule face stiff penalties, including a Dh15,000 fine for the first offence.
Additionally, the employer should pay Dh1,500 to employees who are forced to work during the midday break, and they will not be able to issue new labour cards or employ new workers.

He said that the Ministry of Labour's inspections will be held daily until the last day of the midday break rule to ensure compliance with the UAE labour law.
"The inspection department will carry out 30,000 guidance and inspection visits until September 15 to raise awareness of the importance of implementing the midday break rules and to see how many companies are complying with or violating the break rule," he said.

The guidance and inspection visits will take place at different worksites starting from 10.30am until 12.30pm in addition to lectures, which will be conducted across the UAE, to explain prevention of and protection against heat stress and work-related injuries.

"Such programmes and campaigns will help reduce injuries and heat stress and will improve health and safety standards to achieve the welfare of labourers," he added.



Midday break awareness campaign launched in Abu Dhabi

UAE Launched Midday Break for Workers Working in the Sun

Abu Dhabi: The Ministry of Labour is conducting an educational programme to raise the awareness of employers and workers about the "dos and don'ts" with regard to the three-month-long mandatory midday break for those working in the sun during the summer, a senior ministry official has said.

Under the rules, which went into force on June 15 and run until September 15, workers can lay down their tools for a break from 12.30 pm to 3pm. Employers must provide first aid, air-conditioners, sunshades and cold water for workers.

Qasim Mohammad Jameel, acting Director of Guidance at the ministry, said that the awareness programme features 125 on-site lectures and campaigns and will be conducted with government and private sector stakeholders and partners.

He added that the break during the hottest hours of the day was introduced to ensure the health and professional safety of labourers working in the direct sun and prevent dehydration and other health risks, including sun stroke and heat exhaustion.

Nine mobile labour care units will tour construction sites to deliver the programme which also include the screening of a specially created film.

The ministry of labour teams, he added, have already approached 5,000 workers in Abu Dhabi, 2,500 in Dubai and more than 1,000 in Sharjah, educating them about the best methods to keep safe from heat-related illness.

He said ministry inspectors will also visit building sites to make sure the rules are observed.

In the same context, health authorities have also launched "heat safety" programmes aimed at increasing awareness of heat stress and prevention of heat illness among employers and workers, and explaining how to reduce heat-related illnesses. Such programmes will not only help reduce heat-related illnesses but will also improve health and safety standards and ensure the welfare of workers.
