Each committee consists of committee
members appointed from among experts who
have relevant knowledge and experience inhigh pressure gas or LPG safety.
In response to requests from the president of
KHK, the technical committee decides basic
policies for establishing the technicalstandards.
The technical standards are then establishedby each standards committee section inaccordance with the basic policies, and thedevelopment and issue procedures maintainfairness and openness as the fundamental
rule.
During fiscal 2013, the following standards
were established or reviewed.

2) Inspection, Examination and Accreditation① Inspections for Pressure Equipment
The High Pressure Gas Safety Act stipulates
that the person who has manufactured/
imported a container or accessory shall apply
for the Container/Accessory Inspection. We at
KHK conduct these inspections.
In addition, for preventing explosions or otheraccidents, the act defines "equipment for highpressure gas production (including storage
tanks) “which particularly requires

Copyright© The High Pressure Gas Safety Institute of Japan“inspections of its design, material quality, andthe process of its manufacturing", as"Designated Equipment." KHK undertakes
mandatory inspections of such DesignatedEquipment at each manufacturing process.
KHK undertakes technical assessments inadvance to obtain Ministerial special approval,
and also offers services for certification andexamination as a part of its optional activities.
In fiscal 2013, the number of application forinspection of containers increased by 16.9%
and that of accessory equipment increased by
1.8% compared to the previous fiscal year
respectively.
In addition, the number of application forinspection of designated equipment increased
by 13.1%, while the number of application forhigh pressure gas equipment test decreased by
3.7%, compared to the previous fiscal year
respectively.

Pre-Assessment of Accredited
Completion/ Safety Inspection Executor
This pre-assessment undertaken by KHK ispart of the statutory service related to the
Ministerial approval of accredited completion
inspection executor and safety inspection
executor.
Class 1 high pressure gas producers who
obtained Ministerial approval as a result of
this pre-assessment can replace completion
inspections or safety inspections that are
conducted by prefectural or municipal
governments with self–inspections by theapproved producers themselves. When the
self-inspections are conducted, the results
shall be submitted to jurisdictional prefectural
or municipal governments.

Copyright© The High Pressure Gas Safety Institute of Japan3) Education① Statutory Training
By the High Pressure Gas Safety Act, highpressure gas producers are required toestablish a safety management teamconsisting of members with a designated highpressure gas production safety management
certificate, depending on the type and scale ofprocessing equipment and the type andvolume of gas produced. To train certified
personnel, KHK offers lectures on eachcertificate type, and retraining for existing
members of safety management teams.
In addition, KHK also provides training
courses for the following certificates: highpressure gas sales safety chiefs required at
specified high pressure gas dealers,
transportation supervisors required fortransportation of specified amount of specified
high pressure gas, and specific high pressure
gas operation safety chiefs required for storage
and consumption of specified high pressuregas beyond the designated capacity.
As for the LPG Law-related activities, KHK
offers the following courses: training andretraining of LPG installation engineers for
LPG piping facilities used for general
consumption, retraining of retail operation
chiefs, training and retraining of LPG filling
operators, as well as training of safety
operators and inspectors of facilities designed
to consume LPG.

Number of applicants for statutory training
Among the statutory training, while there
was a decrease in the number of the5qualification training from 44,828 in fiscal
2012 to 44,316, the number of applicants forthe re-training (compulsory training)
increased from 50,126 to 51,334 in fiscal 2013
and the total number of applicants of thestatutory training also increased from 94,954
to 95,650. The number of statutory training
applicants are cyclically increased anddecreased as shown in the figure above, andthat of the fiscal 2013 corresponded to thegreatest year.
② Other Trainings
During fiscal 2013, KHK held periodical
seminars including basic lectures on highpressure gas safety (8 types at 28 locations),
and organized 15 on-site lectures on voluntary
safety activities depending on the needs ofeach business facility.
③ Publications
KHK publishes books related to highpressure gas safety such as high pressure gas
safety act, technical standards, and textbooks
for training. During fiscal 2013, KHK
published 125 types of books, accounting for a
total of 198,999.

4) Qualifying Examination
The High Pressure Gas Safety Act and LPG
Law stipulates that the Minister of Economy,
Trade and Industry or prefectural governors
must be responsible for conducting the highpressure gas production safety management
examination, the high pressure gas sales
safety chief examination, and the LPG
installation engineer examination, dependingon the classification of examinations.
However, the actual implementation of suchexaminations was transferred to KHK from
the Minister of Economy, Trade and Industry
and prefectural governors.
The total number of applicants for suchexaminations was 58,231, an increase of 1.3%
compared to 57,467 from the previous fiscal
year.

hydraulic fatigue/explosion tests of pressure
equipment including transportable containers,
undertaking research and development toenhance high pressure gas safety. In addition,
KHK are working on researches commissionedby the government and incorporated
administrative agencies.
In fiscal 2013, KHK conducted four
researches commissioned by the Ministry of
Economy, Trade and Industry as well as by the
New Energy and Industrial Technology
Development Organization (NEDO). The
following is the overview of the researchcommissioned by NEDO.

Research and Development on theStandardization of Composite Cylinders
and Tubes for Stationary Storage
In the testing of composite cylinders andtubes which are used in hydrogen stations,
there is a big gap between an ambient
temperature pressure cycling test, one of theevaluation methods, and actual use conditions.
A further sophistication of the evaluation
methods, including the fatigue design ofcomposite cylinders and tubes, is desired.
Under the circumstances, it is aimed to
improve and sophisticate (1) the evaluation
techniques of Composite Cylinders and Tubes
for Stationary Storage, (2) the evaluation
techniques of CFRP, (3) the fatigue design
methods of Composite Cylinders and Tubes for
Stationary Storage and (4) the safety
inspection techniques of composite cylinders
and tubes, in order to contribute to theresearch and development for the
standardization of composite cylinders andtubes for hydrogen stations.

Under the commission of METI, KHK records statistics of high pressure gas- and LPG-related
accidents, based on the number of reports submitted in accordance with the regulatory
requirements of the High Pressure Gas Safety Act and the LPG Law.
The number of high pressure
gas-related accidents has been
increasing in recent years, and2011 in particular saw a sharp
rise in the number as a resultof the Great East Japan
Earthquake. Althoughdecreased in comparison to2012, the number of accidents
in 2013 has still remained
relatively high. Particularly,
major accidents involving
explosions at industrial

Similarly, the number of
LPG-related accidents has also
remained high in recent years,
at around 200 per year.
Particularly, accidents
involving commercial kitchenequipment are showing an
increasing trend, and a rise in
the number of accidents caused
by deterioration due tocorrosion or CO poisoning has
also been recorded. In order toprevent such accidents fromoccurring, it is increasingly
essential to provide effective
information to LPG users, facility
owners and possessors.
