Handheld Receiver

Large LCD display shows digital wind speed, temperature and beaufort chart clearly. Anti-slip rubber on two slides helps users hold the receiver in place during work. User-friendly interface and simple button design allows you to operate the device easily with only one hand.

When the wind reaches a certain speed, an alarm will be triggered, and it will continue as long as high wind is detected. The alarm buzzer located on top of the receiver can effectively warn users at the level of 90 dB.

Low Power Consumption

We use innovative low-power consumption wirless technology on WR-3. The battery power consumption is only 20-30 uA in normal condition and 35 mA peak current during data transmission. 3.6V Lithium battery with 2400 mAh capacity can run the sensor for 4 years.

4-year long battery life reduces the maintenance cost significantly. Low battery indicatior on the display monitor will show up when battery capacity is lowered than 10%.

Car mechanics feeling the heat

Gulf Times - ‎Jun 16, 2013‎
A visit to garages will reveal that the workers perform their duties without adequate protection from the heat - thereby getting exhausted in no time - due to the nature of their work. It’s not just construction labourers who have to work in simmering conditions during the summer. Those employed in garages and automobile workshops, too, face the heat as they are exposed to the harsh weather.
A visit to garages will reveal that the workers perform their duties without adequate protection from the heat - thereby getting exhausted in no time - due to the nature of their work. 
While regulations of the Ministry of Labour provide some relief to the construction workers as they cannot be made to work between 11am and 3pm during the summer, it is not clear if this rule applies to garage mechanics as well.
“It is doubtful if there is any such restriction on the duty hours of garage workers in the country,” said a Sri Lankan worker at a garage in Bin Mahmoud.
The sight of garage workers toiling under scorching conditions is common on Garage Street, Industrial Area. “It is high time restrictions are put in place on outdoor as well as indoor duties for garage workers during the day in summer,” said a worker at a workshop in Najma.
Those employed in automobile workshops in the Industrial Area felt it would help if their duties were scheduled in the evening during summer.
A section of garage operators, too, had similar views. One of them, who has a garage on Wakalat Street, said it would do his company a world of good if the authorities enforced regulations to reschedule the summer timings of automobile workshops so that they could start work in the evening. This, he added, would lead to greater productivity as the workers would be able to perform their duties more efficiently.
It is also felt that garages need to have only emergency staff in the morning hours during the summer. 
Senior personnel involved in the business said a large number of vehicle owners would keep their vehicles in garages and workshops for annual maintenance before leaving for their summer holidays. As a result, the garage workers would end up handling extra load during this season. “Due to the adverse weather conditions, work gets delayed at many workshops,” a garage owner said.
Sources in the industry said some workers would refuse to return after going on leave due to the poor working conditions in many garages here. Operating in such unhygienic and unhealthy environs takes a toll on workers’ health, said a senior mechanic of a Doha garage. 
He said due to the good working conditions of his workshop that the company, which represents a major automobile brand, was able to retain its workers.



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.



Ohio State warns workers of heat stroke

NBC4i.com - ‎Jun 5, 2013‎

The Ohio Bureau of Workers' Compensation is taking a preventative approach to heat-related illness, which affects thousands of Americans every year. According to Occupational Safety and Health Administration, at least 30 workers died in 2012 associated with heat exposure.

This June, the Division of Occupational of Safety and Hygiene is visiting construction and additional outdoor work sites to pass out water and informational cards explaining the warning signs and risks of heat-related illness, such as heat stroke.

Heat stroke can occur following exposure to high temperatures resulting in dehydration. If the core body temperature exceeds 105 degrees Fahrenheit, serious complications involving the nervous system can occur. Symptoms often begin with chills and dizziness, and can escalate to nausea, confusion and disorientation, which require immediate medical attention before loss of consciousness results. The state's month-long program stresses "Hydrate, Cover, Rest" in the printed message to those who toil under a hot sun for prolonged periods of time.



Workers Feeling the Heat in Middle East

GCC countries take actions against heat stress among labourers

The end of May heard the UAE Ministry of Labour announce that outdoor labourers, such as those on construction sites, would be given a mandatory two-and-a-half hour break from 12.30pm to 3pm be tween June 15 and September 15 so as to avoid the the most extreme heat of the day.

The ministerial decision also stated daily working hours could not exceed eight and labourers who usually worked in the open could not be redirected to indoors duties during the break.

The announcement of the UAE’s now annual restriction was closely followed by Saudi Arabia, where temperatures reached 50 degrees Celsius in June, and where the ban takes effect from July 1.

According to the Kingdom’s Ministry of Labour, the ban will be in place between midday and 3pm during the summer months and will see violating individuals and companies fined up to SAR 10,000 ($2,675) on each occasion.

Oman's midday work ban will be in place throughout June, July and August – with Qatar, Bahrain and Kuwait having made similar arrangements.

While the imposition of such restrictions in the region over the last few years has gone some way to placating calls for improved working conditions for labourers, a recent survey has found that not enough is being done by employers to educate their workforce on the risks posed by working in extremely hot conditions, and measures they should take to minimise the threat.

UAE-based company Dulsco, which provides human resources services, conducted the survey of 700 workers during an annual summer medical camp backed by the Dubai Health Authority, and found that almost two-thirds of blue-collar workers in Dubai claim they are not regularly trained by their employers about heat-related health issues despite working outdoors.

Only 36% reported learning about health issues posed by working outdoors in heat from their employers, while 24% relied on general knowledge or experience, and a further 16% were informed by friends, colleagues or the heads of working camps, where many low income expat workers live.

About one-third also said that they did not drink enough water to stay hydrated in summer, with 80% not taking frequent breaks and only 28% having healthy food and juices.

However, Dulsco said that the research showed an improvement in workers' understanding of heat-related health issues as around 63% of the 700 workers surveyed said they were aware of the health risks during summer – an increase of 24% compared to last year.

Workers also reported a better understanding about typical summer conditions such as dehydration, food contamination, hygiene, skin diseases and sunstroke and many also were keen to learn exercises, healthy food and ways to keep their bodies cooler during the hotter months.

"Many companies across the UAE are increasingly investing in the health and welfare of their employees through continuous health awareness drives," said Mubarak Kozhikkal, senior manager of Dulsco Medical Services.

"Summer is especially a challenging season with many people involved in outdoor work and therefore, educating their teams on health risks is extremely important."
