Usage Of Personal Protection During Haze

Usage Of Personal Protection During Haze





Personal Protection

Personal protection is required when going outdoors during a haze. The appropriate protection is a device that prevents the inhaling of airborne particles causing the haze. The various protections commonly used are the surgical face mask and the respirator.

Airborne particles causing haze may be as small as 2.5 microns. The use of the surgical mask will not prevent one from inhaling the small airborne particles. Therefore the recommended protection is the use of the respirator.          


Use of Respirators

A respirator is a protective device worn covering the nose and mouth and is used to reduce the wearer’s risk of inhaling hazardous airborne particles. Respirators work better than surgical masks as they seal better and restrict more polluted air from entering the nose and mouth. They also come with the right filter to remove fine particles found in a haze. The N95 respirator may be used as protection during the haze. The respirator filters the small airborne particles and can reduce exposure to the haze. The N95 mask is effective only if used correctly.


The use of N95 masks increases effort in breathing.  For some people, the use of N95 mask may cause discomfort breathing, tiredness or headache. This may be due to the mask causing increased resistance to breathing, and a reduction in the volume of air breathed. For most people this is not serious however in precautions must be taken in certain categories of people.


Precautions to Using the Respirator


·  Elderly people, people with lung or heart conditions
·  People with claustrophobia
·  People with lung diseases such as asthma or emphysema
·  Women in the later stages of pregnancy

 N95 mask is not suitable for pregnant women and children. Persons with chronic lung or heart conditions who feel uncomfortable when wearing the N95 masks should stop doing so and consult a doctor before carrying on.


Facial hair, like a beard or mustache, can affect the respirator's ability to protect as it comes between the wearer’s face and the respirator's seal. It can also get into the respirator's valves can allow contaminated air to leak into the respirator face piece. Long hair may also get between the respirator seal and wearer’s face allowing contaminated air to leak into the respirator.
