Chemicals - certain chemical are utilized in the cooking of paints , varnishes , laminates , adhesives , and solder resin . Some chemicals used to make insulating material , froth mattress , packaging materials , and upholstery can induce this asthma attack .

enzyme – specific enzyme used in the provision of detergent and flour conditioners can spark off this asthma .

alloy - exposure to metallic element , particularly platinum , chromium , and nickel sulfate , can cause this asthma .

Respiratory Irritants - vulnerability to special gases such as chlorine gas , sulfur dioxide , and smoke can irritate the respiratory tract.(2 )

Asthma symptoms begin when the lungs get annoyed or inflamed . Inflammation cause a sequence of reactions in the respiratory nerve pathway that subjugate the diameter of the airway , resulting in difficulty in breathing . In the case of occupational asthma , lung inflammation leads to an allergic reaction to a particular substance . It usually take some sentence to develop .
