Guidelines for the Necessary Measures to
Prevent Health Impairments
to Workers Due to Chemical Substances, Etc. (2000) |
In Japanese |
|
1.Purposes
|
|
More than 50,000 types of chemical substances
are now being used in industries, and 500
to 600 new chemical substances are introduced
each year. As these chemical substances may
impair the health of workers who are exposed
to them, their usage results in a significant
number of health impairments every year.
In some cases, workers are injured by being
exposed to chemical substances because of
their leakage or improper handling during
storage, safekeeping or transportation processes
in the workplace.
|
|
In recent years, moreover, we are facing
new public concerns involving chemical substances,
such as the effects of
environmental endocrine disrupting chemicals
on health as well as health impairments stemming
from flon alternatives.
|
|
Under these circumstances, employers who
manufacture or handle toxic chemical
substances,
etc., (hereinafter referred to as "Employers")
are required to improve the management
of
chemical substances, etc., at workplaces
to prevent health impairments to workers.
(In this paragraph, chemical substances,
etc., mean chemical substances, preparations
containing chemical substances and
other
substances which are liable to pose
hazards
to worker health (hereinafter referred
to
as "Chemical Substances, Etc."),
as stipulated in Item 1, Article 58
of the
Industrial Safety and Health Law (Law
No.
57 of 1972) (hereinafter referred to
as the
"Law").
|
|
The management of Chemical Substances, Etc.,
at workplaces is to be carried out in accordance
with the provisions of the related cabinet
order and other regulations on the basis
of the Law. Moreover, as specified in Item
1, Article 58 of the Law, Employers are to
assume responsibility for conducting their
own toxicity studies, etc., and for undertaking
the necessary measures to prevent the impairment
of worker health caused by Chemical Substances,
Etc. (hereinafter referred to as "Measures
to Prevent Health Impairment") based
on the results of such studies.
|
|
In order for these Measures to Prevent Health
Impairment to be carried out appropriately
and effectively, it is further required
that
specific implementation methods are
to be
established at relevant workplaces.
|
|
With the aim of contributing to preventing
worker health impairment and in compliance
with Item 2, Article 58 of the Law
requiring
that Measures to Prevent Health Impairment
are to be carried out appropriately
and effectively,
these guidelines have been prepared
to specify
the principle items to be implemented
and
to otherwise promote the voluntary
management
of Chemical Substances, Etc., by Employers.
In carrying out Measures to Prevent
Health
Impairment, it is desirable that Employers
adopt an approach that meets the actual
conditions
prevailing at individual workplaces
while
still basing the management plan on
these
guidelines.
|
2.Formulation, Etc., of Chemical Substances
Management Plan
|
(1) |
Employers are to formulate a plan that stipulates
the items to be implemented for the
appropriate
management of Chemical Substances,
Etc. (hereinafter
referred to as the "Chemical Substances
Management Plan"), and to make
workers
aware of this plan.
|
(2) |
The Chemical Substances Management Plan is
to include the following items:
|
a. |
Matters related to observing all related
industrial safety and health laws and
ordinances
concerning the prevention of industrial
accidents
caused by Chemical Substances, Etc.
(including
notices based on same; hereinafter
referred
to as "Laws and Ordinances")
and
the Chemical Substances Management
Plan,
etc.
|
b. |
Matters related to the formulation and implementation
of Measures to Prevent Health Impairment
based on the results of risk assessment.
(In this paragraph, risk assessment
means
to obtain information on the toxicity
of
Chemical Substances, Etc., to evaluate
the
possibility and extent of health impairment
to which workers may be subject depending
on the type and degree of toxicity
of said
Chemical Substances, Etc. (hereinafter
referred
to as "Toxicity, Etc.") and
the
extent of worker exposure to said Chemical
Substances, Etc., and to examine measures
to prevent or reduce exposure to said
Chemical
Substances, Etc.; hereinafter the same).
|
c. |
Matters related to the appropriate management
(including the prevention of leakage
and/or
theft of Chemical Substances, Etc.)
of storage,
safekeeping and transportation (including
transportation outside the workplace;
hereinafter
the same) of Chemical Substances, Etc.,
used
in workplaces.
|
d. |
Matters related to the prevention of worker
health impairment caused by exposure
to said
Chemical Substances, Etc., in the event
of
any substantial leakage and/or overflow
of
Chemical Substances, Etc., from any
facilities
that produce or handle Chemical Substances,
Etc. (hereinafter referred to as "Facilities").
|
e. |
Matters related to health management such
as understanding the health impact
said Chemical
Substances, Etc., may have on workers
who
produce or handle such Chemical Substances,
Etc.
|
f. |
Other matters related to the prevention of
worker health impairment caused by
Chemical
Substances, Etc.
|
(3) |
In preparing the Chemical Substances Management
Plan, Employers are required to reflect
the
views and opinions of workers as elicited
through health committees and by other
means.
|
3.Identification of Toxicity, Etc., and Risk

Substances,
Etc., outside experts concerning the
Toxicity,
Etc., of Chemical Substances, Etc.,
specialist
organizations dealing with the same,
and/or
by other means.
|
(4) |
Further, any party who is an Employer, and
who transfers or otherwise provides
Items
Subject to Notification, is to have
a person
who is properly qualified with the
required
knowledge to prepare safety data sheets
for
Chemical Substances, Etc. (hereinafter
referred
to as the "Person Qualified to
Prepare
Chemical Substances, Etc., Safety Data
Sheets")
prepare the same, and to issue it to
the
party to whom said item is transferred
or
otherwise provided. Moreover, the party
who
transfers or otherwise provides Chemical
Substances, Etc., other than Items
Subject
to Notification is to examine the Toxicity,
Etc., of said item(s), and is to endeavor
