Most employers will use a combination
of control methods. There are advantages and disadvantages to each type
of control measure when considering the ease of implementation,
effectiveness, and cost. For example, hygiene and social distancing can
be implemented relatively easily and with little expense, but this
control method requires employees to modify and maintain their behavior,
which may be difficult to sustain.
On the other hand, installing clear
plastic barriers or a drive-through window will be more expensive and
take a longer time to implement, although in the long run may be more
effective at preventing transmission during a pandemic. Employers must
evaluate their particular workplace to develop a plan for protecting
their employees that may combine both immediate actions as well as
longer term solutions.
Here is a description of each type of
control:
Work Practice and Engineering
Controls–Historically, infection control professionals have relied on
personal protective equipment (for example, surgical masks and gloves)
to serve as a physical barrier in order to prevent the transmission of
an infectious disease from one person to another.
This reflects the fact that close
interactions with infectious patients is an unavoidable part of many
healthcare occupations. The principles of industrial hygiene demonstrate
that work practice controls and engineering controls can also serve as
barriers to transmission and are less reliant on employee behavior to
provide protection.
Work practice controls are procedures
for safe and proper work that are used to reduce the duration, frequency
or intensity of exposure to a hazard.
When defining safe work practice
controls, it is a good idea to ask your employees for their suggestions,
since they have firsthand experience with the tasks.
These controls should be understood
and followed by managers, supervisors and employees. When work practice
controls are insufficient to protect employees, some employers may also
need engineering controls.
Engineering controls involve making
changes to the work environment to reduce work-related hazards. These
types of controls are preferred over all others because they make
permanent changes that reduce exposure to hazards and do not rely on
employee or customer behavior. By reducing a hazard in the workplace,
engineering controls can be the most cost-effective solutions for
employers to implement.
During a pandemic, engineering
controls may be effective in reducing exposure to some sources of
pandemic influenza and not others. For example, installing sneeze guards
between customers and employees would provide a barrier to transmission.
The use of barrier protections, such
as sneeze guards, is common practice for both infection control and
industrial hygiene. However, while the installation of sneeze guards may
reduce or prevent transmission between customers and employees,
transmission may still occur between coworkers.
Therefore, administrative controls
and
public health measures should be implemented along with engineering
controls. Examples of work practice controls include:
Providing resources and a work environment that promotes
personal hygiene. For example, provide tissues, no-touch trash cans,
hand soap, hand sanitizer, disinfectants and disposable towels for
employees to clean their work surfaces.
Encouraging employees to obtain a seasonal influenza
vaccine (this helps to prevent illness from seasonal influenza strains
that may continue to circulate). Providing employees with up-to-date
education and training on influenza risk factors, protective behaviors,
and instruction on proper behaviors (for example, cough etiquette and
care of personal protective equipment).
Developing policies to minimize contacts between
employees and between employees and clients or customers. More
