Development and ergonomic evaluation of overall for oil tank cleaners

According to the environment inside the oil tank and the requirements on the cleaning work and protection,a new protective overall for oil tank cleaners was produced with face fabrics available,which is fit and comfortable by means of functional and structural design,specially in active parts such as waist,knees and openings of sleeve and leg.Ergonomic examinations showed that the flexible peats with a maximum stretch of 5 cm in the waist make the overall wearer feel fit no matter the wearer is standing straight or squats down and then stands straight;an average stretch of 2.5 cm,for slightly bending over;and an average stretch of 4.6 cm,for bending over or embracing the knees.The design of sleeve and leg openings of the new overall with triangle cut piece and sealed by zip differs little from that of the common elastic sealing in terms of skin covering,but with improved comfort.For the new overall,activity limitations are down and flexibility is up.This research work offers a better overall for oil tank cleaners,which integrates the protection,functionality,fitness and comfortability.
