Metal fume fever is a condition in which the patient has influenza type symptoms – a rise in temperature, chills, aches and pains, nausea and dizziness. And ‘it caused by exposure to smoke of some metals – commonly zinc. Other metals that have been reported to bring on symptoms of metal fume fever include copper and cadmium.

Sayhealthy.net – Symptoms begin to appear several hours after exposure. Metal fume fever caused by exposure to zinc fumes is transient, and recovery is usually complete within a few days. However, the exposure to some metal fumes, such as cadmium, can cause more serious illness, or even death.

Although the cadmium is no longer used as a metallic coating, it can still be found on older plants. Exposure to cadmium fumes may occur during welding repair/maintenance or oxy-gas cutting resulting from decommissioning.

It is desirable to avoid exposure to these fumes altogether by the use of efficient fume extraction. What coating to the steel must be identified before the welding or cutting? zinc or cadmium coatings require special consideration, and if the welding takes place, the coating must be removed both sides of the welding and far enough back to prevent the generation of fumes. In some circumstances, you may need a respirator.

In medicine, fever is one sign of a disturbance in the body. Fever serve as an alarm to let you know that something is going on in our bodies. The cause of the fever can vary, ranging from infections (bacteria, viruses, parasites), allergy, malignancy, trauma, autoimmune diseases. In children and society in general cause of fever is the most common infection. Occupational Medicine in the science known term “Metal Vapor Fever” is a condition in which a worker has a fever caused by metal vapor percent.Keluhan generally resembles flu symptoms are: fever, chills, nausea, vomiting, thirst, headache, fatigue, joint and muscle pain. An acute allergic condition experienced by most welders throughout their working lives.

CASE:

A manufacturer of iron towers, steel plate waves, complained that most employees at the welding taking fever-lowering drugs and a reduction of pain every day. Budget analgesics such antipyretic high. After the visit plan obtained these workers every day exposed to welding fumes, there is no workspace ventilation only the fan to eliminate steam welding results. Unfortunately, fan blowing steam that moves the spatial side where there are others working. The metal vapor that can cause symptoms are noticed most is Zinc Oxide steam generated in the process of welding, galvanizing, symptoms usually occur within 6-24 hours. And will disappear after 24-48 hours without treatment. Other elements such as copper and magnesium also cause similar effects.

Permissible EXPOSURE LIMIT

OSHA standards for steam is 5 milligrams of Zinc Oxide Zinc Oxide vapor per cubic meter of air (mg / m3) for an 8-hour workday.

According to NIOSH 5mg / m3 with an old working 10 hours a day, 40 hours per week, with

Short-Term Exposure Limit (STEL) 10 mg / m3 for 15 minutes.

HOW TO AVOID THE HAZARD?

Avoid head of metal vapor
Do not breathe air containing metal vapor
Use adequate ventilation, exhaust, or both, to clean the air in the respiratory area and its surroundings.
Do not take chances with steam welding results. If ventilation or
Inadequate exhaust wear

respirators (masks) that meet the requirements for cleaning the breathing air.

MASK (RESPIRATOR)

The main recommendation for welding workspace is a technical control with

Local application of exhaust or general ventilation, to reduce the level of exposure to steam Zinc Oxide. But sometimes it is difficult to do so required the use of respirators (masks). Respirator normally used to work in a confined space (confined spaces), such as tanks or enclosed narrow space and in emergency situations. Always use a respirator recommended by the Mine Safety and Health Administration (MSHA) or by the National Institute for Occupational Safety and Health (NIOSH) or the Department of Labor.

MONITOR AND INSPECTION PROCEDURES WORK ENVIRONMENT

– Evaluation of Exposure 8 Hours

Sampling is best carried out for 8 hours or 2 times per 4 hours. Sampling per 30 minutes is not recommended to do. Sampling should be done by people who are trained to use the equipment and the appropriate method. Sampling was carried out in the breathing zone of workers (best describes the air inhaled by workers)

– Evaluation of Short-Therm Exposure Limit

The examination was conducted at the time of the peak concentration of Zinc Oxide vapor is assumed to occur. Do it for 15 minutes or serial with a total time of 15 minutes. The collection is done in the breathing zone of workers. Do at least 3 examinations in one shift, the highest yield which can be summed up as the highest exposure to the worker.

CONCLUSION

Metal fume fever as a result of excessive exposure to vapors Zinc Oxide produced from welding, cutting, grind in galvanized metal.
Metal fume fever is a flu-like collection of symptoms that arise shortly after exposure to metal fumes.
To avoid such complaints, keep the head and avoid inhalation of vapors metal. Use good ventilation or exhaust. If ventilated difficult to carry out using the appropriate mask.
Unknown long-term effects of this disease.
