... The periodic maintenance of fume cupboard is an essential part to avoid the degradation capacity of the ventilation, in turn can reduce the accident. The study conducted by Hussein et al. (2017) revealed some accidents happened in their chemical laboratory in 2016 due to lack of maintenance and safety test by qualified personnel. The accident was chemical spillage, accompanied by water flood. ...
Accident can happen anytime and anywhere. To avoid the accident, the hazard must be reduced and controlled. In this study, the method of Hazard Identification, Risk Assessment and Risk Control (HIRARC) was used in order to minimise the hazard. This study was conducted in Chemistry Laboratory, Faculty of Chemical Engineering, UiTM Pasir Gudang Campus. This laboratory was chosen because most of the first-year students did their experiments which involved chemicals and apparatus in this laboratory. This study started with identified the potential hazards, followed by risk assessment, which is to calculate the risk level and lastly implementing the risk control, if necessary. From the results obtained, there were 8 major routine activities in this laboratory. The highest risk level value was 6, which contributed from 3 activities. The activities are handling chemicals in the fume hood, disposing acidic waste chemicals and preparing solutions. There are some recommended controls measures need to be implemented to make sure the risk level can be reduced in the future. In conclusion, the HIRARC method used in this study is a useful method to identify the potential hazard in order to minimised the accident rate.

... This work aims to determine the toxic metals in tobacco, tobacco smoke and ash from selected imported cigarettes brands in Iraq using smoke absorption by deionized water method and examination metals concentration using (EDX) and atomic absorption devices. This research spans a series of research specialized in safety aspects to lay the groundwork for human health and environment [21][22][23][24][25]. ...
... As a general rule, every chemical used in the laboratory must be considered as a hazardous material and safety precautions must be taken into accounts. Additionally, sufficient information must be obtained about all chemicals in the inventory of all laboratories [4][5][6][7][8][9]. However, the story was different in one of our laboratories as there was an accident took place as a result of unknown chemicals were put in a furnace and heated to 400°C upon request from a postgraduate student. ...
... It is worth noting that we have reported and raised many similar safety issues in some research facilities in Iraq and suggested some feasible recommendations to offer a safer workplace environment [13][14][15][16][17][18][19][20][21][22][23]. ...
... However, if the ventilation system incorporates fans on both the supply and exhaust ducts, the capacity of the fans need to be adjusted so the fan on the exhaust duct is pulling air out of the laboratory with greater force than the fan pushing fresh air into the laboratory. Adjusting the air flow in this manner creates negative pressure ventilation, allowing sufficient air flow into the room while minimizing the possibility of health effects due to the presence of chemical hazards [4][5][6][7][8]. ...
... This article is mainly concerned with safety matters. Researches on chemical safety has been of interest to the researcher and has published many articles in such subjects, several important recommendations was stated in these articles [15][16][17][18][19][20][21][22][23][24][25][26]. ...

society has an interest in promoting ethical behavior in its scientific community, learning institutions and chemical enterprises may minimize training and education programs on chemical ethics.Al Rodda et al have previously emphasized the importance of robust scenario-based training that provides low-risk opportunities to practice ethical behavior to strengthen people's resolve to act when bigger ethical problems arise. In this manuscript, we present a straightforward roadmap to promote transparency as a means to bolster ethical behaviors of people and amenities. This roadmap, if implemented appropriately, could assist not only in maintaining research transparency and integrity but in avoiding or minimizing the effects of dangerous laboratory accidents.
... One of the most important hair problems is the loss of sulfur, which can be done when adding hydrogen peroxide to ammonia to increase hair bulge and improve its acceptance of the dye. [15].Researchers focused on topics directly related to human health and safety and published many articles in this regard, several important recommendations was stated in these articles [16][17][18][19][20][21][22][23][24][25][26]. ...
The major threats to human health from heavy metals are associated with exposure to highly toxic heavy metals such as arsenic, lead, cadmium, chromium, mercury, as well as some other elements. Heavy elements are important in the formation of living organisms and play an important role in their growth they are toxic. High concentrations of heavy metals may cause health problems. A natural hair dye called (Henna) extracted from a famous plant in Iraq also called henna plant from Basra Governorate. Acid digestion was carried out to Henna sample using nitric acid with hydrochloric acid in a ratio of 2.5:1. The main purpose of acid digestion is to free the elements by destroying the organic components in order to be analyzed in atomic absorption. For the same purpose, water extraction was carried out for henna sample using deionized water. Large proportion of the sulfur element was identified using EDX analysis method for hair dye sample, while atomic absorption analysis shows that acid digestion which was carried out to henna sample was not effective enough to dissolve all the elements. This conclusion was proved according to the presence of some elements in the precipitation resulting from acid digestion. Several treatments may be needed to insure the optimum extraction for the elements from the selected samples.
